The Genuine Dining Co has secured a five-year deal with Pinewood Studios, which is expected to generate £10m in total turnover.
The contract will see the foodservice company take over the catering at the venue based in Iver Heath, Buckinghamshire.
The British film and television studio will have five dining venues with an estimated occupancy of up to 3,000 people.
Rebecca Gibson, business development manager at the Genuine Dining Co, said: "This is an exciting new venture for the company, full of possibilities and fun; we truly are a perfect match."
The new contract will also be managed by Genuine Dining's sister company Genuine Events, which will deliver year-round events including Christmas parties, conferences and weddings at the studio's Victorian mansion Heatherden Hall.
