EXCLUSIVE: Tom Hanks and Rita Wilson Adorably Squabble Over Their Box Office Showdown

ET spoke with the cutest Hollywood couple around about their new movies, 'Sully' and 'Brother Nature,' both released this weekend. 'Sully' took home the No. 1 spot at the box office.

Could Tom Hanks and Rita Wilson be any cuter?

Hollywood's most adorable duo attended the Stand Up To Cancer 2016 Telethon on Friday, where they broke up the night's serious nature with a light-hearted chat with ET's Denny Directo about their movies.

Hanks and Wilson, who have been married for 28 years, revealed what it felt like to have dueling films come out this weekend: Sully and Brother Nature, respectively.

"We're battling it out... He's got Sully, I've got Brother Nature -- two completely different movies, though," Wilson explained. "Like, maybe you see Sully, and then you do a late show of Brother Nature or vice versa."

"Taran Killam vs. Clint Eastwood, all the way," Hanks retorted, pointing out two of the stars of the conflicting flicks.

Joking aside, the 60-year-old actor admitted that, after all these years, it's become easier for both him and his wife to ignore critics because, simply, "there's nothing you can do about it."

"I did another movie not too long ago, and when the reviews came out, someone came up to me and said, 'Well, the New York Post didn't hate your movie too much,'" Hanks revealed. "So, it's better to have it the other way around."

Though they weren't literally duking it out, one half of the happy couple did come out the clear winner: Hanks' Sully flew to the front of box office, taking home the weekend's No. 1 spot with $35.5 million. Brother Nature, on the other hand, was only released in select theaters on Friday.

Stand Up To Cancer is an event that holds special meaning in the Hanks household. Wilson, 59, revealed that she had been diagnosed with breast cancer in April 2015. She underwent a double mastectomy, and in December, the singer-actress said she was cancer-free.

"I want to say, first of all, that I'm thankful for every single day," Wilson told ET at the SU2C event. "It's encouraging. For me, it's all about awareness and about raising money. I had incredible doctors. I was initially misdiagnosed and I got a second opinion on my pathology [which] showed that I did have cancer. So with that very, very early diagnosis I was able to take care of it and get it all done."

The Girls star has gushed about how supportive her husband was after her diagnosis, but for Hanks, it's clear he wouldn't have had it any other way. "No one should go through this alone," he said on the red carpet. "That not only goes for the person who is carrying it and in bed for a very long time, but there's also the people who love them."
