EXCLUSIVE: Ahead of the Cannes market, Bankside Films wins the international rights to the Oren Moverman project Raised eyebrows.

As previously announced, Geoffrey Rush (The King’s Speech), Sienna Miller (21 bridges) and Charlie Plummer (moon fall) are set to star in the 1970s feature film about the later years of comedy icon Groucho Marx.

The film will follow Steve (Plummer) as he enters the world of aging comedian Marx (Rush) for his dream job, under the watchful eye of Erin Fleming (Miller) – a young woman who had resumed her personal life and professional of Groucho. The ensuing generational power struggle culminates in a gritty horror comedy.

The messenger and filmmaker Rampart Moverman is directing from a script he co-wrote with Steve Stoliar, based on his memoir Eyebrows Raised: My Years in Groucho’s House.

Bankside will discuss the project with buyers at the upcoming Cannes market. ICM Partners and CAA Media Finance manage national rights.

The film is produced by Miranda Bailey and Moverman. Julia Lebedev and Eddie Vaisman of Sight Unseen Pictures recently joined the production team, who will serve as executive producers alongside Stephen Kelliher and Sophie Green of Bankside.

Stephen Kelliher said: “We were immediately obsessed with the unique and compelling true story of Raised eyebrows which sheds light on one of the most complex and compelling relationships in showbiz history. Making this film with such a prestigious team is a real honor.

Oren Moverman added, “I am thrilled and grateful that Bankside is joining our fierce cinematic family in bringing Groucho back to the movies. Their focus on independent quality speaks for itself. Nowadays, that means everything.

Miranda Bailey commented: “Groucho Marx was an icon who transcended local boundaries – we are delighted to present this project at the Marché du Film and share it with international buyers to reach today’s global audience.
