And, as we all remember, they all looked like they had an absolute ball making the flick. We'll let Oprah break it down for you.

"I have a lot of actor friends [...] like I was on set the other day with 'Wrinkle in Time,' and I said to Reese [Witherspoon], 'So, Reese, how many movies have you done?' and she said, 'I don't know, I don't know ... hundreds, y'all.'" she recounted to People magazine's Jess Cagle. "So, I was like, 'Oh, God. Please don't ask me how many movies I've done.' I think I've done five!"

"It's rare that I feel intimidated, but I felt intimidated," she concluded.

In fact, Oprah has acted in upwards of 14 films, including movies made for TV, so she's being modest.

Classic Oprah!
