After his failure in prime-time cop drama, the Wookie next turned his talents to the all American sitcom. He plays a fun-loving but highly strung Wookie adopted by an average white family living above a porn shop. Wookie added a new catch phrase to the sitcom pantheon of catch phrases. Unfortunately, the writer's strike of 1980 stopped production of "What you talkin' 'bout, Wookie?" and only the pilot was made. Unable to re-sign Wookie because of his other contractual obligations, the producers retooled the comedy and turned it into the laugh-a-minute fun-fest we grew to love: Alf!
Update: 1) you probably need to get QuickTime to watch these movies.
2) On the internet archive page that comes up after you click on the movie link above, select the MPEG4 file to the right. The stream thing doesn't work, so don't click on that.
