Affleck suited up in a royal blue tux, while his on-screen leading lady Pike, who is currently pregnant with her second child, dressed her baby bump in an Altuzarra black gown, reported Ace Showbiz.
They were joined by co-stars like Emily Ratajkowski who was red hot in a strapless gown, Missi Pyle who went with a black glittery dress with plunging neckline and slit, and Casey Wilson who opted for a red dress.
Neil Patrick Harris and Tyler Perry were in attendance as well.
Directed by David Fincher, 'Gone Girl' opened the 52nd film festival at Alice Tully Hall.
It is a story about Affleck's character Nick Dunne who is accused of murdering his wife, Pike's Amy, after she went missing on their fifth wedding anniversary. Adapted from Gillian Flynn's best-selling novel of the same name, it will hit US theatres on October 3.
