Pacino was supposed to be the dancing expert and Anwar the novice, but after three weeks of training for the pivotal scene, the Brit admits she was the one with the tango skills, not her partner.
Anwar reveals Pacino, who played a retired, blind Lieutenant Colonel in the 1992 film, was too busy to attend rehearsals - and his lack of training led to a painful experience for his co-star.
She tells U.S. news show Access Hollywood Live, "It was a bit dodgy. I have a few sort of half-broken toes still. It was interesting... (but) it's Al Pacino, for God's sake; I couldn't exactly complain. I was afraid... He was incredibly nice to me."
