Spoiler Warning: If you're one of the few people that didn't rush out and see Guardians of the Galaxy on opening weekend, then be warned that spoilers follow. And if you truly don't want to be spoiled until you see the film, you should probably stay off the Internet in general, because major media sites are tweeting bootleg video of the after the credits scene like crazy.
In the Guardians of the Galaxy after the credits scene, The Collector is shown battered and bruised in the remains of his destroyed museum. Cosmo the Dog licks The Collector's face, and Howard the Duck asks, "What do you let him lick you like that for? Gross."
There has been much speculation about who was the voice of Howard the Duck. Many rumors have suggested it was Nathan Fillion, but Fillion's cameo is actually earlier in the film during the prison scene.
According to Ain't It Cool News, director James Gunn revealed to them that Howard the Duck is actually voiced by none other than Seth Green, who is known for his voice work in Family Guy, Robot Chicken, Phineas and Ferb, and Hulk and the Agents of S.M.A.S.H.0comments
