Potter made her screen debut in 1994, on CBS soap opera The Young and the Restless as Sharon Newman.
She later appeared in several feature films, including Con Air (playing the wife of Nicolas Cage's character) and starring opposite Robin Williams in Patch Adams.
In 1998, she played the love interest of doomed distance runner Steve Prefontaine in the movie Without Limits, and also appeared in the British comedy Martha, Meet Frank, Daniel and Laurence (1998).
[9] In 2001, she had two major roles, co-starring with Freddie Prinze, Jr. in Head Over Heels, and in the thriller Along Came a Spider with Morgan Freeman, based on the James Patterson best-seller.
In 2009, Potter became a cast member of the new TNT series Trust Me which was cancelled after the first season due to low ratings.
Potter played the role of Kristina Braverman in the comedy-drama Parenthood, receiving critical acclaim for her performance in the fourth season.
[16] In 2016, Counting Crows' frontman Adam Duritz confirmed that the band's song Mrs Potter's Lullaby, from the album This Desert Life (1999), was written about an imaginary version of her, as they had never met.
They became friends, and a tape he forgot he gave her on the night of the recording ended up salvaging the song, which the band felt they had ruined during post-production and had decided to not keep on the album.
[20] In March 2015, Potter's husband joined the US Navy Reserve as a physician, with the starting rank of Lieutenant Commander.
