James Brolin knows that people think Christian Bale is his doppelganger, but he wonders why.

On the aftershow of Thursday’s Watch What Happens Live, Brolin was asked by a fan who called into the show about the internet’s opinion that Bale looks like him, even more than his own son, actor Josh Brolin.

“Have you ever heard that?” host Andy Cohen asked in the clip below.

“Many times,” said the actor, whose latest project is Netflix’s Sweet Tooth, “and I don’t get it.”

Cohen and actor Tony Goldwyn, who was also a guest, said they understood it after seeing the elder Brolin up close.

The Traffic actor said he hadn’t officially met Bale, but he had run into guys he thought looked like they could be his brother.

Speaking of family, Brolin said that his dad told him there was “a 10,000 to 1 chance against you being successful” when he decided to go into acting.

He had overcome his painful shyness in childhood — “I couldn’t even give a book report” — but someone spotted him in his hometown of Los Angeles, and put him in a commercial. Brolin said he was under contract with Fox by the time he was 19, so he was set on what he wanted to do.

Eventually, his father came around.

“Then he started making reservations at restaurants under my name,” said Brolin, who’s now 83.

Brolin, who married Barbra Streisand in 1998, has had staying power in the entertainment business. He won an Emmy back in 1970, for his work on the medical drama Marcus Welby, M.D., and is next scheduled to appear on Netflix’s upcoming family drama series Ransom Canyon, which costars Minka Kelly and Josh Duhamel in what’s been described by the streamer as “Virgin River meets Yellowstone.”
