Greta Gerwig has admitted that playing the iconic role of Linda in Arthur makes her nervous.
The US actress, who starred with Ben Stiller in Greenberg, is stepping into the famous shoes of Liza Minnelli for the remake of the 1981 film, which starred Dudley Moore as the eponymous character.
"I do feel pressure - my gay male friends have put me under a lot of pressure, telling me Liza is not to be outdone," she revealed.
But she claimed: "I'm not trying to outdo her in anything, or make my portrayal like hers. Liza is iconic, and it seems that when a role has been done by someone like that, there is a feeling like a lot of people are going to hate it.
"I'm just going to do the best that I can and I would like to think that I have her blessing."
Greta has been trying to get in touch with Liza to speak to her about the role.
"Hopefully I'll get to have lunch with her very soon, so that would be very exciting. I think all my musical theatre friends will completely lose it when that happens," she joked.
Arthur also stars Russell Brand and Helen Mirren.
:: Greenberg is out on DVD and Blu-ray on October 4.
