When movies go man-to-man
2.Mel Gibson and Danny Glover in Lethal Weapon
Unquestionably the best pairing in the history of the overdone incompatible police comedy genre (perhaps we should just call them copedy movies now?), Gibson's Riggs and Glover's Murtaugh are ridiculously enjoyable police sergeants.
Gibson is constantly, explosively funny while it's hard not to sympathise with Glover -- while laughing at him at the same time. Good old-fashioned laughs.
