Watch Clifford (1994) Official Trailer

What's the difference between Clifford and a pit bull? One will tear your heart out, scare your friends and wreck your house. The other one is a dog.

When his brother asks him to look after his young son, Clifford, Martin Daniels agrees, taking the boy into his home and introducing him to his future wife, Sarah. Clifford is fixated on the idea of visiting a famed theme park, and Martin, an engineer who helped build the park, makes plans to take him. But, when Clifford reveals himself to be a first-rate brat, his uncle goes bonkers, and a loony inter-generational standoff ensues.
