Taking place at the Odeon West End in Leicester Square, Anne Hathaway wore a long blue robe, said cheerily Press: "I was rained on and almost tripped on the red carpet."
The 25-year brown romantic drama is about "a young woman who has been in and out of rehabilitation for the past 10 years to return home for the weekend wedding of his sister."
Asked about the Oscar buzz surrounding the film, Hathaway told the AP he was "really cool but a little premature to get excited about."
Also present at the verification step was hyped "Crash" actress Thandie Newton, who was accompanied by husband Ol Parker.
