Whilst Warner were understandably champing at the bit to get a second film made, beardy star Galifianakis was concerned at the prospect of pushing the same gag too far.

“I think (the original) worked because there was some fresh jokes,” said Galifianakis to IGN. “They've become so saturated now, comedies. Cursing has become the new wit and it just drives me crazy when I see that. The Hangover had some cursing in it and all that stuff, but my character didn’t curse. I asked if he could not curse. There's little elements like that that maybe were kind of new to people. Also, nobody knew the cast and that in a weird way helped.”

But surely with the same director and cast, the old chemistry would resurface? Not necessarily, according to Galifianakis.

“I'm not running to do The Hangover 2” he continued. “I told Todd, the last thing I want is the Police Academy chain all of the sudden. You've got to be careful with something like that. The movie's really good, why bother with a sequel? Obviously, the reason is executives have Bentleys to pay for. I would love, love, love to work with those guys again but the script has to be good!”

All fair points, and hopefully ones that suggest Phillips will have had to have worked hard on the script to get Galifianakis back on board. Bradley Cooper however, was far less tricky…
