Lynda Carter says she's no Wonder Woman when it comes to trying to balance a busy acting career with raising a family.

"I do a movie every year and that's plenty right now because I don't want to miss these moments with my children," says Carter, 49, who today spends much of her time raising son James, 12, and daughter Jessica, 9, with lawyer hubby Robert Altman.

Carter, who rose to fame in the 1970s as the titular character of TV's Wonder Woman, says on this coming Monday's Intimate Portrait (Lifetime, 7 pm/ET) that she realized the importance of staying close to her family while away in Vancouver shooting the short-lived 1994 Stephen J. Cannell drama series Hawkeye.

"It was the most miserable time of my life," recalls Carter. "I have come to the conclusion that I cannot be separated from my family. All life really is [is] just one giant moment, an eternal moment."

Still, Carter seems to be enjoying work in TV-movies, such as last year's Family Blessing, in which she played the romantic interest of a younger man. "It was an interesting thing to do," she offers, "and it was also [a] taboo that I liked to expose."
