It's hard to believe that it's been 14 years since the first 'Hangover' film.

A lot has changed in that time - especially for one of the film's stars Bradley Cooper, who went from relative obscurity to clocking up Oscar nominations for roles in the likes of 'A Star is Born', 'American Sniper' and 'Silver Linings Playbook'.

Cooper's latest role is as the iconic composer Leonard Bernstein in the biopic 'Maestro' - but he's not averse to returning to the franchise that made his name.

He said in a new interview: "I would probably do Hangover IV in an instant. Just because I love Todd [Phillips], I love Zach [Galifianakis], I love Ed [Helms] so much, I probably would."

The last 'Hangover' film was released a full decade ago in 2013, but Cooper admitted that the likelihood of director Todd Phillips returning to helm another sequel was unlikely, saying "I don’t think Todd is ever going to do that."

'Maestro' was directed and co-written by Cooper himself, but the first trailer generated controversy when fans slammed the prosthetic nose worn by him as perpetuating a Jewish stereotype.

Bernstein's family later came out and defended Cooper on that charge, saying "It happens to be true that Leonard Bernstein had a nice, big nose. Bradley chose to use makeup to amplify his resemblance, and we’re perfectly fine with that."
