Carey Mulligan was happy her friend Keira Knightley was by her side on the red carpet at the opening of the BFI London Film Festival on Wednesday night.

The pair star in Never Let Me Go, the movie chosen to open the two-week long celebration.

An Education actress Carey said she was pleased Keira was with her otherwise sometimes being in the lime light alone can be scary.

They were joined at the event by rising star Andrew Garfield, who is also in director Mark Romanek's thriller.

Other celebrities out in Leicester Square included actor Jim Broadbent and director Joe Wright.
