The 73-year-old Oscar winner was set to appear on the home-shopping channel on Saturday to promote her new book on aging, “Prime Time.” But the day before, she learned her segment had been canceled.

In a statement posted on her website, Fonda says QVC told her of receiving “a lot of calls” from viewers criticizing her opposition to the Vietnam War and threatening to boycott the show if she appeared.

QVC spokesman Paul Capelli confirmed Fonda’s canceled appearance. But he added, “It’s not unusual to have a schedule change ... with little or no notice.”

“Prime Time” will be published next month.
