Who doesn't love Murtaugh and Riggs? They were arguably the best crime fighting duo to come out of the 80s and 90s. Danny Glover played Murtaugh through four films. He was a cop that just wanted his pension and for the days to go a little easier. Then there was Riggs. He was a partly suicidal cop that lived for the action. That dynamic, written by Shane Black, became the basis for practically every buddy cop movie to come later. The last Lethal Weapon film to be made and released was Lethal Weapon 4 in 1998 (unless you count the unofficial sequel from the gang in It's Always Sunny in Philadelphia). That movie wasn't notable for much except introducing American audiences to Jet Li. The movie did an OK job of getting everyone together and closing out the series, but the series had lost the refreshing taste the first two flicks left in people's mouths. Lethal Weapon 4 still managed to be a hit and with so many studios looking at old franchises for new material, Lethal Weapon 5 was talked about for a brief while. Richard Donner, Joel Silver, Mel Gibson, Danny Glover and Shane Black were all set to return (this was 2011). Some reported that no one could agree on a story, others reported it had to do with scheduling while many others claimed it was Gibson's public image that slowed things down. There was even a screenwriter hired to pen a reboot. It's unlikely now that Lethal Weapon 5 will ever happen (Donner and Gibson seem to have given up hope), but it doesn't mean the movie wouldn't be great. Here's five reasons why Lethal Weapon 5 would be awesome...
