The Rock took part in a Twitter Q&A earlier today to promote his new movie, Pain & Gain. Here are some highlights:

Being offered the main role in Transformers 4: "Michael Bay offered me Transformers, but I was unavailable due to Hercules. Then Wahlberg was offered the role."

Rehab: "Rehab is coming along well. 3 hernias repaired leads to lots of swelling.. in the cash & prizes area. #GreatBallsOfFire ;)"

Partnering with Pain & Gain co-star Mark Wahlberg again: "After Hercules, I'll partner up w/ Wahlberg - cool HBO project, then possibly FAST 7 - haven't decided yet on that."

If he'll ever do a movie with Will Smith or Denzel Washington: "I love those guys. Will's been a buddy for years. I'm sure we'll do a movie together. Denzel is an inspiration."

His WrestleMania match with John Cena: "Mania may have been my last match. The 3 year goal was to come in & elevate the @WWE. Then proudly 'do the honors'."
