In the neon-drenched underbelly of Los Angeles, where palm trees claw at smog-choked skies and the echo of gunfire lingers like a bad hangover, the ’80s action blueprint was forever etched in celluloid. It was 1987, and a rogue LAPD detective named Martin Riggs—played by a wild-eyed Mel Gibson—crashed into the life of family man Roger Murtaugh (Danny Glover), turning routine busts into high-octane bromances laced with dark humor and darker stakes. Directed by Richard Donner, Lethal Weapon wasn’t just a movie; it was a cultural Molotov cocktail, blending Dirty Harry‘s grit with 48 Hrs.‘s odd-couple spark. Over the next decade, three sequels followed, each amping the absurdity: South African drug lords in Lethal Weapon 2 (1989), armored-truck heists and internal affairs drama in Lethal Weapon 3 (1992), and a poignant family reckoning with Chinese triads in Lethal Weapon 4 (1998). The franchise grossed nearly a billion dollars worldwide, spawned endless catchphrases (“I’m too old for this shit!”), and cemented Gibson and Glover as the ultimate screen duo—Riggs the suicidal loose cannon, Murtaugh the by-the-book dad whose “shit” quota only grew with age. But as the credits rolled on that fourth installment, with Riggs and Murtaugh sailing into a sunset of sorts, fans were left with a bittersweet void. For 27 years, whispers of a fifth chapter swirled like exhaust fumes, teased by cameos, TV reboots, and half-baked scripts. Then, in July 2021, amid the grief of Donner’s passing at 91, Gibson dropped a bombshell: he was stepping behind the camera to direct Lethal Weapon 5, honoring his mentor’s unfinished vision. It shocked fans, reignited dreams, and thrust the project back into development hell—where, as of December 2025, Gibson is still fighting tooth and nail to drag this franchise back to life, refusing to let the buddies’ final bow fade to black.

The revelation came like a jump-cut surprise in a buddy-cop montage. Donner, the visionary who’d helmed Superman’s silver-screen flight and helmed all four Lethal Weapon entries, had been quietly scripting the sequel since the late ’90s. In interviews as recent as 2020, the octogenarian teased it as his swan song: “It’s the last one—Riggs and Murtaugh one more time, but with heart.” He’d enlisted Gibson early, the pair bonding over script tweaks in Donner’s Malibu manse, where storyboards mingled with memorabilia from The Goonies. But on July 5, 2021, Donner slipped away from a cardiac event, leaving behind a half-formed blueprint and a pact with Gibson: if anything happened, Mel would take the reins. “Dick was my brother,” Gibson later reflected in a tear-choked tribute at the 2022 Saturn Awards, his voice gravelly from years of on-screen shouts. “He handed me the keys to the Batmobile of buddy cops. I owe him this ride.” The announcement landed amid Gibson’s own career renaissance—fresh off directing the $400 million-grossing Hacksaw Ridge (2016) and starring in The Professor and the Madman (2019)—but it was laced with melancholy. Fans, starved for closure after the 1998 finale’s open-ended family focus, flooded social media with montages: Riggs’ reckless dives off cliffs, Murtaugh’s exasperated eye-rolls, Joe Pesci’s Leo Getz yapping through chaos. “If Mel directs, it’s gospel,” one viral thread declared. “Donner’s ghost in the machine.”

Yet limbo loomed large. Warner Bros., the studio that birthed the series under New Line Cinema’s banner, had greenlit a 2016 TV reboot starring Clayne Crawford and Damon Wayans—axed after two seasons amid backstage beefs and middling ratings. A 2022 pilot with Seann William Scott and Justin Hartley fared no better, DOA in test screenings. Feature-film talks sputtered: early 2020s scripts floated legacy nods, with Riggs and Murtaugh mentoring millennial cops, but COVID shutdowns and executive churn buried them. Gibson, undeterred, dove in post-Donner’s death. By late 2021, he’d assembled a writers’ room, blending Donner’s outline—a tale of aging detectives facing a tech-savvy cartel—with fresh beats: Riggs confronting fatherhood ghosts, Murtaugh navigating empty-nest blues. “It’s funny, but it’s also pretty serious,” Gibson teased in a 2024 Inspire Me podcast sit-down, his Aussie twang laced with resolve. “Tackles a couple of hard issues—loss, legacy—but with the laughs that made us us.” Enter Jez Butterworth, the Oscar-nominated scribe behind Ford v Ferrari and Spectre, who polished drafts in 2023. “Jez got it,” Gibson enthused at the 2024 Golden Globes after-parties. “The script’s the best yet—emotional gut-punch with explosions.”

By May 2025, the duo reunited at Fan Expo Philadelphia, a comic-con cornucopia where Gibson and Glover—now 69 and 78, respectively—hugged like long-lost kin amid a sea of cosplayers. Flanked by stars like John Cena and William Shatner, they fielded Screen Rant queries with trademark banter. “We’re too old for this shit—twice over!” Glover quipped, his baritone booming as Gibson nodded, eyes twinkling. “But Dick’s script? It’s got heart. Mel’s directing—gonna make him proud.” The crowd erupted, but Gibson tempered the triumph: “We did two or three drafts—it’s fun, emotional. But the studios? Problems. Age, deals, the whole mess.” Insiders echoed the snag: Glover’s health (he’s battled diabetes and arthritis, limiting stunts), Gibson’s directorial schedule clashing with Flight Risk (delayed to mid-2025, a Wahlberg thriller where Mel helms the cockpit), and Warner’s franchise fatigue amid DC reboots. “Mel’s singing for his supper,” a production source confided to Closer in January 2025. “Script’s gold, but logistics? A minefield. Danny’s essential—can’t recast Murtaugh—but at 78, action’s risky.”

Undaunted, Gibson’s crusade pressed on. September 2025 brought a “disappointing” whisper from director Allan Ungar (Bandit, 2022), who’d chatted with Mel post-Flight Risk reshoots. “He’s got a plan—always does,” Ungar told MovieWeb. “But development at WB/New Line? Stalled. Do we need it? Lethal Weapon 4 wrapped poignant.” Gibson countered in a rare X post—his feed a rarity since 2010—sharing a Donner throwback: “Dick’s vision lives. Fighting the good fight. #LethalWeapon5.” Fans rallied: petitions hit 500,000 signatures, TikTok edits of Riggs’ mullet-era madness racked billions of views, and Glover, ever the elder statesman, teased at MegaCon Orlando in February 2025: “One more ride? Wouldn’t that be wonderful?” Their chemistry, forged in four films’ worth of near-death dives and dad-joke defusions, remains the saga’s secret sauce. Gibson’s Riggs: the widower whose grief-fueled recklessness masked vulnerability, leaping from buildings with a suicidal grin. Glover’s Murtaugh: the anchor, his “too old” mantra evolving from punchline to poignant as kids grew and crises mounted. Sequels layered lore—Pesci’s neurotic Leo, Rene Russo’s psychologist Lorna, even Jet Li’s triad terror— but the core duo’s fraternal fire burned brightest, grossing $950 million on a shoestring $110 million budget.

The stakes? Sky-high. At 69, Gibson’s no stranger to redemption arcs: post-2006 scandals (DUI rants, anti-Semitic tirades) that tanked his star, he clawed back with Edge of Darkness (2010) and The Beaver (2011), but Hacksaw Ridge‘s Oscar haul in 2017 sealed his directorial chops. Critics hail his eye for chaos— visceral violence tempered by human frailty—perfect for a Lethal Weapon swan song. Glover, 78, embodies endurance: from The Color Purple (1985) to Jumanji reboots, his activism (anti-apartheid crusades, UN ambassadorship) mirrors Murtaugh’s moral compass. Rumors swirl of cameos: Pesci as a grizzled Leo, perhaps a digital Donner Easter egg. Plot teases? A modern cartel twist—drones over LA freeways, Riggs mentoring a hotheaded protégé—blending ’80s excess with 2020s edge. “It’s the end,” Gibson vowed at a 2024 charity gala. “Riggs and Murtaugh retire—for real this time.”

As December 2025 chills Hollywood’s canyons, Gibson’s battle rages: script locked, cast circling, but greenlight elusive. WB eyes a 2027 slot, post-Dune: Messiah, banking on nostalgia’s billion-dollar pull amid Top Gun: Maverick‘s afterglow. Fans, from forum vets to TikTok teens discovering the originals on Tubi’s August 2025 free-stream binge, chant for closure. “Bury it? Hell no,” Gibson growled in a leaked set visit clip. “Dick’s laughing from above—’Get off your ass, Mel!'” In a town of reboots and requels, Lethal Weapon 5 stands as testament: some bonds defy dust. Gibson’s not just directing; he’s resurrecting ghosts, one hip-fired shot at a time. The buddies’ last stand? Overdue, but worth the wait. Lock and load—Gotham’s got nothing on this.
