John Krasinski doesn’t usually fret about reviews. But for his new film “IF,” he is terrified of the response from two people: His 7 and 10-year-old daughters.

“I’ve never been worried about two reviews more in my life,” Krasinski told The Associated Press in a recent interview. “I’m genuinely terrified. I hope it goes well.”

“IF,” about a young girl (Cailey Fleming) and her neighbor (Ryan Reynolds) who can see everyone’s imaginary friends including those that have gotten left behind, is one of this summer’s major studio releases opening on May 17. In a landscape full of brands and franchises, it’s the rare original idea that has the backing of a big studio, Paramount, and an ambitious scale and scope. It was shot largely in New York by Oscar-winning cinematographer Janusz Kaminski and blends live-action and animation with an army of celebrity voices including Steve Carell, Phoebe Waller-Bridge, Matt Damon, Jon Stewart, Maya Rudolph and the late Louis Gossett Jr.
