Witherspoon wows in red as she outshines Ben Affleck and pregnant Rosamund Pike at the premiere of Gone Girl

She's usually the main star, but Reese Witherspoon remained behind the scenes on the highly anticipated David Fincher film, Gone Girl, serving as a producer instead.

But the 38-year-old actress outshone the stars of the movie – on-screen husband and wife Rosamund Pike and Ben Affleck – at the premiere during the New York Film Festival on Friday.

The Wild star was ravishing in a red halter style dress that highlighted her slender physique, as Rosamund swathed her heavily pregnant figure in a flowing black gown. 

Reese also donned simple but elegant gold heels and channelled old Hollywood glamour with her blonde hair styled in sleek luxurious waves, with a side part. 

Meanwhile, Rosamund, 35, sported black pointed-toe pumps, complimenting her dress, which featured a turtleneck and thigh-high split.

She wore her hair slicked back in an elegant knot, opting not to wear any accessories. 

The actress kept her look simple, letting her blossoming baby bump take centre stage instead.

Rosamund is due to give birth in November to her second child with partner Robie Uniacke. 

Meanwhile, Ben, 42, looked dapper in a stately blue suit with a bronze tie.

Also present was Gone Girl star Emily Ratajkowski, who can be seen in Robin Thicke’s Blurred Lines video.

She highlighted her stunning physique in a smashing red gown that also showcased her cleavage.

Gone Girl stars Neil Patrick Harris and Tyler Perry were also pictured, all suited up.

In the mystery thriller film, Ben stars as Nick Dunne, whose wife Amy vanishes on their fifth wedding anniversary.

Her disappearance becomes the focus of an intense media circus and Nick sees the spotlight turned on him when it’s suspected that he may not be innocent. 

The flick is based on the bestselling novel by Gillian Flynn and hits theatres October 3. 

Amy’s weight can be seen fluctuating during the movie, and Rosamund has discussed having to gain and lose pounds for her role.

'I think that was one of the big testing parts of getting the role,' the beautiful blonde said on The Today Show. 

‘I flew to St. Louis to meet David [Fincher]. I think he was watching what I ordered. Is this girl going to be ready to… gain the weight? So I showed him that I was.

'I had to fluctuate three times because of the way it was scheduled,' she added. 'I had to fluctuate about 12/13 pounds - gain it, lose it, gain it, lose it, gain it, lose it.'

The mother-of-one initially thought she could do it 'healthily' with foods such as avocados and macadamia nuts.

But she easily moved on to milkshakes, preferably chocolate vanilla malt milkshakes.

Meanwhile, Emily, 23, commented triumphantly on nabbing the role of Andie Fitzgerald in an interview with Vanity Fair. 

‘I didn’t want to act in high school because I was sick of auditioning for Nickelodeon, Disney mean girls, or the cheerleader,' she said. 

‘I came back to it when I had enough leverage to pick and choose. I got a dream role in a dream film.'
