20. JIM BELUSHI AS DET. SGT. ART RIDZIK IN RED HEAT (1988)
It’s not that Jim Belushi isn’t believable as a police officer; we’ve seen plenty of coppers inside the local Dunkin’ Donuts that look just as disheveled and also tell unfunny jokes. The dog in the 1989 action-comedy K-9? Now there’s a fitting crime-fighting partner for the slovenly funnyman. Unlike Arnold Schwarzenegger, Belushi’s stunt-loving colleague in Red Heat, K-9’s German Shepherd doesn’t make your boy Jim look like he stumbled onto the wrong film set. Schwarzenegger has worked with plenty of unworthy on-screen sidekicks, but Belushi remains the most ill-minded. And the former Governator once co-starred with Sinbad, for crying out loud!
