It may have taken place in his hometown, but Colin Farrell missed out on the Irish premiere of his new movie 'Seven Psychopaths'.
Farrell was unable to attend due to schedule commitments in New York.
'Green Mile' star Rockwell (44) said he loved working with father-of-two Farrell.
It was his first time teaming up with the Dubliner on-screen.
"I had never worked with Colin before and it was a joy," he told the Irish Independent.
Although he picked up a few sightseeing tips from Farrell, it was a jet-setting visit for Rockwell.
"He told us to go to Kehoes pub, but (unfortunately) I'm leaving tomorrow."
"We're all goofs, so we had a great time filming. They're just a cool group of guys, very fun and professional," added Rockwell.
