The Garden State actor-turned-director stepped behind the camera for the upcoming remake of the 1979 crime comedy, and he is still in awe at landing three "legends" to star as retirees who scheme to rob a bank.

"I can't think of three actors I love more than Morgan Freeman, Michael Caine, and Alan Arkin," he gushed on U.S. breakfast show Today.

But filming in the Big Apple proved to be more difficult than he had imagined.

"It's really hard to make a movie with them in New York!" he laughed. "We shot in New York City in the summer, so imagine walking down the street with them - they stop traffic, the paparazzi are everywhere.”

"We tried to do these action sequences and it's like, the earth stops, because Morgan Freeman in particular, people really think he's god," Zach continued. "People like, start crying when they see Morgan Freeman! We're like, 'We're trying to film, can you just cry on that sidewalk?'"

Despite the frequent interruptions, Zach insisted the veteran actors were nothing but professional, and were all eager to complete their own action sequences.

"They're just so fun and silly...," he shared. "They didn't want their stuntmen to do anything. They're doing all the stunts, they're running around. They laughed and they had so much fun... They don't do a lot of action comedy..."

And Zach emerged from the shoot with a fun memento after winning a bet with Morgan.

He explained, "Morgan Freeman, I made a bet with him once: he didn't think I was gonna wrap him as early as I did, and when I won the bet, he had to do my outgoing voicemail message...!"
