Alfonso Ribeiro thinks a "Fresh Prince of Bel Air" reboot would be "impossible" without James Avery.
The late actor - who sadly died aged 68 in 2014 after undergoing open-heart surgery - played Uncle Phil on Will Smith's classic US sitcom, and his co-star doesn't think a revamp could work without him.
Alfonso told PEOPLE.com: "I think it's impossible with James Avery being gone... Without him, everything that Will and Carlton did would mean nothing -- it's a bunch of kids acting stupid.
"There had to be jeopardy, and the way Uncle Phil was going to handle it was the other side of making what Will and Carlton did work.
"Without him, there is no "The Fresh Prince of Bel-Air". I'm sure a [reboot] could happen, but I continue to say I think it's very unlikely."
Meanwhile Alfonso, 47, joked while producers probably wouldn't be able to afford to get Will back on board, he also doesn't think fans want to see it as much as they think.
He explained: "Do we really want to see Will and Carlton in their 40s and 50s? I think people think they want to see that, but I don't think people really want to see that."
The cast are still close friends though, and Alfonso - who portrayed Will Smith's nerdy cousin Carlton Banks on the long-running series and was known for his iconic dance in the series - recently had a reunion with his co-stars more than 20 years after the show went off the air.
He was joined by former castmates, Will, Tatyana Ali, Karyn Parsons, Daphne Maxwell Reid and Joseph Marcell.
