Lena Dunham, creator of HBO's Girls, took the stage at the 2014 SXSW in Austin, Texas on Monday, and spoke out against the unfair way Hollywood treats women.

The 27-year-old star compared the recent success of the show's lead male, Adam Driver, who has been offered roles by Steven Spielberg and the Coen brothers no less, to the lack of dynamic roles her female co-stars have been hoping for.

'People are ready to see Adam play a million different guys in one year – from lotharios to villains to nerds,' she said. 'Meanwhile Allison Williams, Jemima Kirke and Zosia Mamet are still waiting for parts they can get interested in.'

Miss Dunham specifically mentioned co-stars Miss Williams, who plays Marnie, being typecast as the 'all-American sweetheart' and Miss Mamet, who plays Shoshana, being asked to play more 'flighty nood-nicks' - noting that 'both are capable of so much more'

She did make sure to give ample to credit Mr Driver, who plays her zany love interest in the Golden Globe-winning show.

'Adam Driver has had a bang-up year in movies which could not be more deserved because he's a ferocious genius with an incredible work ethic, and I've learned so much from him,' she gushed.
