The 65-year-old single-panel comic strip that no one (not even your grandparents) has ever found funny attempts to fill the "CGI animals that talk and wear sunglasses" gap between Alvin and the Chipmunks: The Squeakquel and Cats & Dogs: The Revenge of Kitty Galore. Not to nitpick or anything, but Marmaduke doesn't even talk in the comic strip. On the plus side, George Lopez voices his second wisecracking Mexican dog after Beverly Hills Chihuahua. Way to typecast yourself! Next up for the actor: voicing CGI versions of Grumpy Smurf (no joke) and Speedy Gonzalez (again, no joke). 87 minutes PG.
