True to form, the Hollywood action hero was forced to dramatically jump off the escalator at the Museum of Modern Art in New York last weekend as it suddenly sped up to 'near-carnival ride speed'.
A source told the New York Post: 'Women started screaming and one did a high-flying jump off, nearly landing on Bruce.'
His publicist, Paul Bloch, who was also on the rogue escalator, added: 'We had to jump, it was going so fast.”
No one was injured and Willis continued to the MoMA screening of his new film Red with co-stars Helen Mirren, Morgan Freeman, John Malkovich, Mary Louise-Parker and Ernest Borgnine.
