Amy Huberman and Claudine Keane also attended the glitzy bash, as well as Downton Abby star, Joanne Froggatt.
The event was hosted in Santa Monica at director JJ Abrams Bad Robot studios for the fifth year in a row by himself and his Irish-American wife, Katie McGrath.
Huberman’s white Lennon Courtney one-piece (?119) proved popular; with it already being sold out in Dunnes Stores if reports are to be believed.
The Irish Film Board And IDA also held their own’ Celebrate The Success Of Irish Cinema’ event the previous night with actors Chris O’Dowd, Fionnula Flanagan and Colin Farrell in attendance.
