A dark and edgy buddy cop movie, “Lethal Weapon” hit theatres on March 6, 1987, becoming an an instant classic, and has withstood the test of time pretty well. Not Mel Gibson’s mullet though, thankfully it begins to shrink before finally vanishing in the later movies. More an action-thriller with some laughs than a slapstick cop movie, “Lethal Weapon” centers around aging detective, Roger Murtaugh, played by Danny Glover, who is paired up with Martin Riggs, an unstable and self-destructive detective grieving over the death of his wife, played by Gibson.
