Scott continued acting in independent films throughout the 1990s. He and TNG guest star Susan Gibney appeared in the 1997 independent romantic comedy Dinner and Driving. The following year, Scott was seen in the drama Girl, as was Rosemary Forsyth. This was followed with a role in The Lesser Evil, a thriller which also featured Anne Haney, Jack Kehler, Richard Riehle, and Marc Worden.
After spending the next few years focusing on television roles, Scott played the title role in the independent thriller Ronnie.

In 2012, Scott recalled working on First Contact while being interviewed for his film Friends with Kids saying; "For me it was rent at the time but it was fun. Jonathan Frakes was directing, he was a really nice guy, but I was never much of a Trekkie. But I like "Star Trek". I really loved the J.J. Abrams movie... I was just never super into it but it's cool that I got to be in one of those movies."
