The "Wonder Woman" star was to present the 'Tree of Life Award' to Ratner at a dinner for the Jewish National Fund but the actor backed out of the event, reported Variety.
A representative for the award function has said that the actor had a scheduling conflict.
"Apparently she is stuck on promo stuff for 'Justice League' for China, and she Is not going to be back in time. We just found this out and everyone is scrambling," said Nina Gorden, who works for the organisation behind the award.
