MEXICO CITY – The Mexican distributor of What If on Thursday was forced to cancel a red carpet event that was to feature Daniel Radcliffe due to crowd control concerns.

Distributor Diamond Films Mexico said Mexico City's civil protection agency ordered it to suspend the event, scheduled for a Mexico City shopping mall. The reason? An unexpectedly large number of fans who turned out to see Radcliffe prior to the event.

"We appreciate the response and enthusiasm for this event," Diamond Films said. "Sorry, but this decision is out of our control."

The event organizer said the rom-com What If will have its Mexico premiere Thursday evening, but without the red carpet treatment.

What If, directed by Michael Dowse and also starring Zoe Kazan, is being released in the U.S. by CBS Films on Aug. 8.
