Starting on a brief interview with Kelly Asbury, one of Gnomeo and Juliet's creators, SFGate ends with a fairly standard list of "films that take liberties with Shakespeare." Linked for those who may not be familiar with every item in the list. There's at least one I'd not heard of.
By the way, if you're wondering about the approach to Shakespeare Mr. Asbury prefers, let me quote him:
"I think Baz Luhrmann's 'Romeo + Juliet' is a work of genius," Asbury says. "I think 'West Side Story' is one of the greatest, if not the greatest, musicals ever put onscreen - or stage, for that matter. I, frankly, like Zeffirelli's 'Romeo and Juliet' very much, too. I grew up with that. ... I loved it; I loved the score, I loved the acting."
I'll let you all make of that what you will. :)
