Chris Candy has a pretty good feeling about how his legendary dad, John Candy, would’ve reacted to his Dunkin’ Super Bowl ad cameo … and he clued TMZ in.

The late comedy star was also a die-hard football fan — even co-owning the Toronto Argonauts — so Chris tells TMZ his father would’ve been immensely proud and blown away by his part in the star-studded commercial during the big game.

Chris admits he had no idea he’d booked a Super Bowl commercial — only weeks later, after production kept getting delayed by wildfires, did he realize how huge it was when he finally showed up on set … and stars were all over the place, including Ben Affleck, who also directed the spot.

Still, Chris managed to snag a moment with Ben when the cameras weren’t rolling, and they had a nice little chat where CC was able to introduce himself … and thank Ben for such a huge opportunity.

As for his Hollywood roots, Chris says he kept quiet about being John’s son — until word got out on set, and suddenly peeps wanted to share how much they loved his dad, who sadly died of a heart attack in 1994.
