Tom Cruise, Penelope Cruz and director Cameron Crowe have mingled with fans at the European gala premiere of the film Vanilla Sky.
Tom and Penelope signed autographs and chatted with fans for about an hour before going into the Empire cinema in London's Leicester Square.
One fan gave a mobile phone to Tom Cruise and said: "Speak to my mum." The star obliged, leaving a message for the fan's mother, who was on another call at the time.
The delighted fan had been queuing for four and a half hours to see Tom and Penelope.
Irish cinemas are holding advance screenings of the film on Thursday.
