‘Clifford The Big Red Dog’ Teaser: That Certainly is a Big, Red Dog You can’t fault Clifford The Big Red Dog for being exactly what it says on the tin. At least, according to the first teaser for the upcoming family film, which features…a big, red dog. The live-action Paramount movie based on the beloved Scholastic book character, Clifford The Big Red Dog brings Clifford to the real world, where — surprise! — he looks a little weird. Clifford The Big Red Dog Teaser I have a weird affection for Clifford The Big Red Dog.
