Jack Black is pumped for fans to rediscover the game Alan Parrish left behind 20 years ago.
ET caught up with the 47-year-old actor at Clayton and Ellen Kershaw's 5th Annual Ping Pong 4 Purpose charity event for their organization, Kershaw's Challenge, in Los Angeles on Thursday, where he shared behind-the-scenes details from the set of his latest movie, Jumanji: Welcome to the Jungle.

When ET's Lauren Zima asked Black if he thinks the sequel will "blow the original out of the water," he played coy, implying nothing can compare to the 1995 classic, which starred the late Robin Williams.
"Now wait a second. You're trying to get me in trouble," said Black, who portrays Professor Shelly Oberon in the movie. "I'm not going to claim to blow anything out of the water. That's Robin Williams. That's hallowed ground. One of the greats of all time."
"But our Jumanji definitely knocks doors down," he added. "It rules! I'm looking forward to unleashing it on an unsuspected public."
While the entire cast seemingly became close on set, Black tells ET that he and Dwayne "The Rock" Johnson, who plays Dr. Smolder Bravestone in the sequel, "had a magical bond."
"Me and Kevin [Hart also] stirred it up. We had good chemistry," he explained. "We were all having a good time. I thought the cast really kicked a** every which way but loose. You'll have to decide who threw down the hardest. It's not a competition but -- yes it is. Of course it is. It always is."
And speaking of competition, we couldn't help but ask Black who's sexier: Johnson or Nick Jonas, who also makes an appearance in the film.

"This is very dangerous. You're pulling me into some very dangerous ground here. I don't know that I'm qualified to judge," he joked. "Obviously Dwayne has the muscular-cher. But Nick is so darn cute. It's too tough to call. Don't make me make that choice."
