Like several other television producers, Stephanie Hagen began her career as an actress, appearing on the Michael Landon show "Highway to Heaven" in 1984 and the cop drama "Cagney & Lacey" in 1985. The following year, Hagen joined the crew of the comedy series "ALF", working as a post-production coordinator for a while, and then an associate producer from 1988 to 1989; she also appeared as an actress on the show for two episodes, but since then has largely left acting behind. Throughout the 1990s, Hagen produced a series of television movies, including "Swing Vote" with Andy Garcia in 1999 and a new adaptation of William Inge's play "Picnic" in 2000. That tale of frustrated female lust was a good dry-run for Hagen's tenure as producer and then executive producer on the hit series "Desperate Housewives". Hagen has worked on 115 episodes of that long-running show, which starred Teri Hatcher, Felicity Huffman, Marcia Cross, and Eva Longoria Parker.
