Girl in Room 13 director Elisabeth Röhm has lavished praise on the late Anne Heche, saying her final performance in the Lifetime movie was a "tour de force".

The much-loved Emmy Award-winning actor Anne Heche died following a car crash that left her in a coma last month.

Speaking to People magazine, Rohm said "it was a really positive experience working with her" and admits it "was really a privilege to direct" Heche.

"These Lifetime movies move very quickly and they're a tough schedule, but she worked really, really hard, and she always brought her A-game, always elevated the other actors, was so generous to all the other actors.

"She was just a total pleasure, a hero for the film. She became a good friend and did a phenomenal job. Her performance is a tour de force, and it was really a privilege to direct her."
