Armie Hammer was notably absent from the world premiere of his new film Mirror Mirror on Saturday (17Mar12) after missing his flight.
The Snow White tale was screened in Los Angeles for the first time and castmembers including Lily Collins and Julia Roberts were there to walk the red carpet.
However, The Social Network star, who plays Prince Charming in the movie, was absent from the line-up and it subsequently emerged the actor had missed his flight to Los Angeles.
He jetted into the city later in the evening in time to attend the afterparty at the Roosevelt Hotel.
The bash also marked Collins' 23rd birthday and she was presented with a large cake in the shape of an apple emblazoned with the words 'Happy birthday Lily'.
The actress celebrates her birthday on Sunday (18Mar12).
Other attendees at the bash included Collins' parents, rocker Phil Collins and his ex-wife Jill Tavelman, as well as Victoria Beckham and actress Molly Ringwald.
