9. Ralph Macchio - Karate Kid II
If you suddenly discovered that your star property could boost this kind of mean moves, there's no way you wouldn't shoe-horn in an entirely unnecessary dancing scene that has absolutely no relevance to the rest of the plot. Which is why it's so easy to forgive the team behind The Karate Kid II for including Macchio's Elvis-like rubber leg skills as a lead in to a much more serious sequence in which he is mugged, assaulted and sees his dance partner threatened with rape. That escalated quickly.
8. Jean Claude Van Damme - Kickboxer
It seems that even Van Damme - a man with breath-taking control over his bodies, even as his age advances - loses all grace and control when confronted with a dance floor. But God bless him, the Muscles From Brussels gives it a good way, snaking his hips around and biting his lip in a horribly cringe-worthy sequence that proves even the most macho of films have something softer at their centre. Until he starts busting out the splits as part of his routine, and you realise it's all just been an elaborate ruse to bed the two women caught in his irresistible grip.
7. Al Pacino - Cruising
If you haven't seen Pacino's turn as undercover cop Steve Burns (a more banal, and less Pacino-like name you will never hear) in 1980 thriller Cruising, it's probably because it's not very good. In fact, it's provocatively bad, and the portrayal of the "gay underworld" of New York City is painted in horribly grotesque, and hugely reductive fashion - not to mention the fact that Burns gets WAY too committed to being undercover. But, it's nice to see Pacino bringing his usual aggression to every part of his role, including dancing, which looks almost like he's limbering up for a fight (which isn't all that surprising considering the amount of drugs he literally just took.)
