Will he have a mullet?
Clayne Crawford is the new Martin Riggs. Though most will recognize Crawford from SundanceTV's RECTIFY, it was 2002's SWIMFAN (14% on Rotten Tomatoes!) where I first noticed his chops.
Not sure why a television reboot LETHAL WEAPON is necessary, but it's on Fox, and they're never ones to shy away from, I'll say, questionable choices. Damon Wayans Sr. will play Roger Murtaugh, so maybe it'll be a THE LAST BOY SCOUT dynamic. I'd be okay with that.
