In "The Vow," Tatum and McAdams star as a married couple whose lives are turned upside down after a serious accident. She's lost much of her memory, but the young husband remains optimistic and vows to make her fall in love with him all over again.
McAdams sees their predicament as very relatable to any relationship.
"Even though it's an extraordinary circumstance and there's a real tragedy that tears them apart, everyone knows that feeling of disconnect," said McAdams.
One romantic element in the film includes lots of chocolate truffles. McAdams says she's still recovering from that day of shooting!
"It took me a little while to come back around but they found their way back into my heart," McAdams laughed. "I was in a coma that day. I've never been on such a sugar high. I couldn't even speak. I couldn't form thoughts in my head."
"I think one of her eyes went lazy, it was getting weird. I was like, 'man she's out of it,'" added Tatum.
Tatum's character looks at life with a "glass is half full" mentality. The actor says he's also like that in real life, well, most of the time.
"Depends on the day, my mood swings, you know, if I've eaten a whole meal or not," joked Tatum.
He said one minute he may think life's terrible, but a cheeseburger can snap him out of his funk and make him love life again.
But the actor hasn't eaten many cheeseburgers these days. He's on a strict diet for his upcoming movie, "Magic Mike," where he plays a stripper.
"I'm having to diet right now? right now life sucks," said Tatum.
Get ready for a whole lot of Tatum in the coming months. After "The Vow", we'll see him in the big screen version of "21 Jump Street" in March. And in June, he's back in action with the sequel, "G.I. Joe: Retaliation," along with "Magic Mike."
