She’s a supporting castmember to leading lady Jennifer Lawrence in The Hunger Games films.

At the world premiere of “The Hunger Games: Catching Fire” on Monday night, Elizabeth Banks stole the spotlight on the red carpet with her gorgeous yellow ballgown.

While Jennifer’s unique backless tunic dress stirred mixed reviews, Elizabeth opted for a classic Hollywood look with a flowing Jason Wu Resort 2014 design that featured cut-out sections to accentuate her slim waist.

Aside from her wedding ring, the actress wore just a GAYDAMAK Koral mini Hand Bracelet as jewellery.  

The 39-year-old mother of two brightened up the rain-soaked carpet on a dark and rainy evening, where thousands of fans endured the chilly weather to catch a glimpse of their favorite stars at the Leicester Square premiere.

Posting an Instagram photo of herself in her limousine on the way to the red carpet, she wrote: ‘On my way to the world premiere of The Hunger Games Catching Fire #London.’

Once at Leicester Square, she was thrilled to see one fan dressed up as Effie.

Speaking to the MailOnline on the red carpet, Elizabeth said: ‘Effie require a total transformation, we spent 3-4 hours everyday but it’s worth it. There’s no Effie without all that.

‘I love to disappear. I love to see her and not me on the screen.’

Joining Elizabeth at the screening were co-stars Jennifer, Josh Hutcherson, Liam Hemsworth, Jena Malone, Sam Claflin and Donald Sutherland.

Jennifer teamed her new pixie cut with an unusual shapeless Christian Dior gown with Smarties-esque embellishments on the skirt.

Jena, who plays Johanna Mason, wore a red Monique Lhuillier gown, while Josh and Liam looked dapper in their suits.

The Hunger Games sequel sees Elizabeth reprising her role as Effie Trinket from the 2012 film adaptation of the Suzanne Collins novel.

In an interview earlier this year, Elizabeth admitted she thought the character of Effie may be gay.

She told The Advocate: ‘Effie Trinket in The Hunger Games might be gay. My vision of the Capitol is pansexual like ancient Rome, where everybody’s doing everybody.

‘I think Suzanne Collins created the character to be nurturing and mothering in her own way, so she’s probably a woman. But I definitely saw a lot of drag Effies last Halloween in West Hollywood!’

The Hunger Games: Catching Fire is released in the UK on 21 November and in the US in 22 November.
