text:  According to Bobby Darin 's agent , Martin Baum , Paul Newman 's agent turned down the part of Fast Eddie . Newman was originally unavailable to play Fast Eddie regardless , being committed to star opposite Elizabeth Taylor in the film Two for the Seesaw . Rossen offered Darin the part after seeing him on The Mike Wallace Interview . When Taylor was forced to drop out of Seesaw because of shooting overruns on Cleopatra , Newman was freed up to take the role , which he accepted after reading just half of the script . No one associated with the production officially notified Darin or his representatives that he had been replaced ; they found out from a member of the public at a charity horse race .
