The actor appeared via video chat from London live on "Good Morning America" today to discuss his new role in the film "Rampage" and becoming a dad again.

"I'm feeling so good and so blessed," Johnson said. "We have a very large contingency plan being over here because the due date is April 25, but mama Lauren, she's been having some Braxton Hicks contractions...so I am on standby ready to jump on the plane. I have talked to our little baby daughter and said, 'Please stay in mama's belly. Just give Daddy two more days.'"

Johnson said, "One of the best parts about meeting Jeffrey Dean's boy is I see him, he comes out and [says], 'That was the best movie ever! And you're way bigger than my dad!'"

Johnson said the action-packed film is built on the bond his character has with an intelligent gorilla named George.

"In the movie, I rescue George when he's a baby and his parents were unfortunately killed by poachers...and we become very close and we have this awesome relationship," he said.

"Rampage" hits theaters this Friday.
