NewYork Tuesday April 12—Dustin Hoffman fan Pamela Crack got the shock of her life when the movie star telephoned her as she was doing her housework.. Crack, 58, said she was “flabbergasted” when she picked up the phone and heard the star at the other end.

“It’s not every day you get a Hollywood superstar phoning you when you’re doing the housework,” Crack told The Sun, “It was a moment I’ll never forget.”

Hoffman was in the back of a London taxi driven by Crack’s husband, Dave, when he made the call after being told Pamela was a fan. Dave Crack later became the star of Hoffman’s speech at the Bafta award ceremony Sunday, where the 62-year-old American actor presented the Best Film award.
