She followed up with roles in the movies Free Country the Movie (1996) and Snapped (1998) before landing a three-episode recurring role as Sandra Reynolds in the television drama Big Apple, in 2001.

2005 brought one on-screen role for Regen, in the movie parting Words.
The following year - 2006 - was her busiest to date, with two-episode recurring roles on Modern Men and So noTORIous; a guest starring role on CSI: Crime Scene Investigation (playing the same role she played in the video game); and appearances in two feature films: Beer League and Nail Polish.
