     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.

     "He said to give him a mention," Hoffman told the audience to a burst of laughter. "Cheers Dave."

Taxi driver Crack said the Hollywood star was a joy to drive from the moment he got into the taxi eating

a cheese and tomato sandwich.

      "I said 'You're that Dustin Hoffman, aren't you?' and he said, 'Yes I am-would you like a sandwich?'

I was a bit surprised but I took a sandwich from him and ate it hungrily."
