Abrams' Lost (with Daniel Dae Kim, Terry O'Quinn and Saul Rubinek), and CSI.
She also has a steady film career. In 1978, she starred in the horror movie The Redeemer: Son of Satan!, in which DS9 regular J.G. Hertzler also appeared. The following year she and TNG star Denise Crosby had small roles as party guests in the film 10. (The film also featured John Hancock, Michael Champion, Lisa Chess and William Lucking).
After acting primarily on television throughout the 1980s, her film credits began stacking up in subsequent decades. She had a role in the 1998 film Judas Kiss, as did Richard Riehle and William Lucking. In 2000, she co-starred with DS9's Wallace Shawn in the film The Prime Gig (also featuring Star Trek: Enterprise guest actor Pat Healy). And in 2003 both she and W. Morgan Sheppard had roles in the little-known film Florida City. Arnette's other motion picture credits include Ladybugs (1992, with Nancy Parsons and Jandi Swanson), Boys Don't Cry (1999), and The Shipping News (2001).
