The Happy Hoofer

When it comes to doing the tango, Arnold Schwarzenegger is no Gomez Addams, but in True Lies the Pumped One trips the light fantastic with both Jamie Lee Curtis and Tia Carrere. However, his costars report that too often the operative word was trips and not light. ''Yes, he did step on my toes in rehearsals,'' says Curtis about her dance partner. ''Yes, it really hurt.'' The experience was even more painful for Carrere, who did one rehearsal with her shoes off. ''Arnold crushed my toes,'' she says. ''It really hurt, but it's all in the line of duty.'' For his part, Schwarzenegger, who took lessons for months with a choreographer, simply smiles and says, ''Dancing is not my specialty.''
