Brent Lang Executive Editor Will Ferrell brought out an adorable fluffy friend named Sophie to hawk his very R-rated new comedy, “Strays,” at CinemaCon on Wednesday. The comic actor and the border terrier teamed up to portray Reggie, a dog who is abandoned by his deadbeat owner (Will Forte). But Ferrell made it clear who has top billing. “My career is going to go on for a long time, but this is the peak for you,” Ferrell said, as the camera operator at the cavernous Colosseum kept cutting back to Sophie’s soulful eyes. If there’s a “Strays 3,” Ferrell joked, the 8-year old Sophie would need to be recast. “That’s an eternity in dog years…and that’s not even Hollywood years,” he said.
