Little Max Page, the 7-year-old mini Darth Vader who delighted America in a 2011 Super Bowl ad, will undergo open-heart surgery tomorrow.

Page, who was born with a congenital heart defect, will receive a new pulmonary valve, and doctors will fix a hole in his heart, according to a report on businessinsider.com.

Although he’s helped raise money for other LA-area kids with heart conditions, Page didn’t find out about his surgery until Sunday, his mother told the site via e-mail.

“I don’t like it and it’s still scary — but I have to,” his mom said he told her about the surgery. “So I think I might as well go through it with a good attitude.”

Page shot to fame in a Volkswagen Super Bowl ad called “The Force,” in which he played a little boy dressed as a helmeted Darth Vader from “Star Wars” (the little boy’s face is never seen).

After trying unsuccessfully to use “the force” to move some household objects — including the family dog — he’s astonished when he magically starts the new family Volkswagen (it’s really his dad, using the car’s remote-control ignition).

According to Page’s mom, he uses his ad fame when he speaks to other sick kids.

“Kids, if you use your FORCE and dream big, you can achieve anything,” he says.

“We may be small — but we’re mighty!”
