Bartha: 'There's more Doug in Hangover 2'

Justin Bartha has confirmed that his character Doug will be appearing in the upcoming sequel to The Hangover, despite being absent from the film's recent teaser trailer.

Bartha also claimed that, contrary to what people might have expected, Doug will be playing a much larger role in the follow-up than he did in the first film.

"Doug isn't lost in this one," Bartha explained to Empire . "There are similar circumstances, but he's a little bit more involved,"

The actor also warned fans of the original not to dismiss the sequel as a simple cash-in, and promised that it would stand up to the high quality of the first film.

"Well your first instinct is to think, 'Sequel - s**tty version of the first film out to make money'," Bartha added. "But as soon as that thought entered my head I remembered; this is a movie written and directed by Todd Phillips with the cast and crew of The Hangover."

The Hangover: Part II is due to be released in US cinemas on May 26, and in the UK on May 27.
