At the AFI Life Achievement Award in 1991 which went to Kirk Douglas, Sylvester Stallone in his tribute to Douglas recalled the filming of the scene where he hits Stallone in the face. After a swing and miss, Stallone jokingly told Douglas to slap him hard. "Let me have your best", whereupon Douglas proceeded to beat Stallone silly. Stallone said "I learned the hard way: never spar with Spartacus".
One night, after filming wrapped, a fire destroyed destroyed several sets, many of the actors' trailers (among them Tim Curry's), all of the costumes, and 21 valuable vintage cars. Production was halted for two weeks while they were remaking all of the costumes. A Universal security guard hired to guard the cars later admitted to setting the fire.
