Michael Rubin is applauding Chris Pratt and David Blaine for going above and beyond with the All In Challenge, and says it's beautiful to see celebs commit their time to the cause.
The Philadelphia 76ers partner, and creator of the Challenge, joined us Friday on "TMZ Live" and couldn't stop gushing about the efforts of Chris, David and a host of others raising money to feed Americans in the pandemic.
Michael says David's a shining example ... the illusionist held an auction and offered to fly to the winner's home for a private magic show, and the winning bid came in at $220,000. But, David didn't stop with one show, he did it three times over -- getting the runner-up and second runner-up to match -- and raised $660k for food charities.
Chris caught the All In bug too ... offering the chance to get eaten by a dinosaur in the 'Jurassic Park' franchise, first as an auction and then again as a sweepstake you can enter for just $10.
Michael says golf icons Tiger Woods and Phil Mickelson also double-dipped with auctions and sweepstakes, with Tiger offering a trip to the Bahamas and putting lessons, and Phil offering the chance at a round with a Masters champion.
So far, the Challenge has raised over $33 million and Michael told us what's impressed him the most about celebs taking charge.
