Acclaimed actress Jacqueline Bisset's new film The Sleepy Time Gal — debuting Friday on the Sundance Channel — took more than two years of on-and-off shooting to finish. Instead of being annoyed at the time consuming process, though, she feels it helped her get closer to her terminally-ill character.

"I was able to get perspective on different times of her life," the 57-year-old tells TV Guide Online. "I was able to work physically on myself to get some of my energy back for the 'well' parts — and then lose it for the 'tired' parts.

"What was great about it," Bisset adds, "was that each time we started to work, I felt really fresh, rather than get worn out on the shoot and [feel] harassed by the production to hurry up and shoot, shoot, shoot. Which so often happens. We had these intense little periods where we'd arrive and attack [a specific] section. I liked it."
