Steve Carell and John Krasinski, iconic for their roles in American sitcom "The Office," recently reunited to work on their upcoming film "IF."

"IF" is about a girl who discovers that she can see everyone’s imaginary friends — and what she does with that superpower — as she embarks on a magical adventure to reconnect forgotten IFs with their kids.

"Blue is played by Steve Carell, who happens to be a dear friend, we actually worked together on this little thing a long time ago," Krasinski said.

In a video shared by Paramount Pictures, Krasinski and Carell shared a hug, saying, "It's so good to see you."

Krasinski told Carell, "I was just telling you guys, has it been years?"
