Actor Paul Rudd continues to be a real-life hero for a 12-year-old boy after his classmates wouldn’t sign his yearbook.

"He’s a really cool kid. I still talk to him," Rudd, 53, told "Extra" in an interview at Comic-Con 2022 after discussing the movie "Ant-Man and the Wasp: Quantumania."

The "Ant-Man" star first chatted with the seventh-grade student Brody Ridder of Westminster, Colorado, after his mother, Cassandra, shared the news in a Facebook post in May.

Cassandra said her son, Brody, came home from school upset because his classmates didn’t sign his yearbook. 

PAUL RUDD SENDS A LETTER TO SEVENTH-GRADE BOY WHOSE CLASSMATES DIDN’T SIGN HIS YEARBOOK: 'THINGS GET BETTER'

"My poor son. Doesn't seem like it's getting any better. 2 teachers and a total of 2 students wrote in his yearbook despite Brody asking all kinds of kids to sign it," she shared online, adding a picture of her son's yearbook pages.

After Rudd heard Brody's story, he decided to send him a letter and a signed "Ant-Man" helmet — which his mother shared images of on Facebook. 

During the "Extra" interview, Rudd discussed his friendly encounter with Brody and called him a "sweet kid."

"My sister told me this story and I said, ‘Is there a way to get in touch with the family?’" Rudd asked.

The Marvel actor noted that it was "months before that story came out. All of a sudden people started calling and emailing" him.
