Sylvester Stallone's 15 Biggest Movies - Ranked Worst To Best

14. Zookeeper (2011)

It's hard not to feel for Sly on this one. As if taking a supporting role in a Kevin James movie was not dehumanising enough, for that very same film to wind up one of your biggest commercial successes ($169.9 million worldwide, making it Stallone's 12th biggest hit) is just salt in the wound. Even so, you shouldn't judge Stallone too harshly; he's but one of a large ensemble of big name actors giving voices to the zoo animals, including Nick Nolte, Adam Sandler, Don Rickles and Cher. And he didn't do too badly getting to voice the lion. It's harmless enough really, but Zookeeper does push that whole 'suspension of disbelief' thing just a little too far. Not so much with the talking animals, but more the fact that Kevin James is able to get with both Leslie Bibb and Rosario Dawson.
