The Foundry, a London special effects team that has created tools used for movies such as Gravity and Guardians of the Galaxy, is expected to sell next year for as much as £200m.

Owners of The Foundry, US private equity giant Carlyle Group, has appointed advisers Arma Partners to find new investors.

Carlyle Group is said to want to realise the investment of the company, which employs more than 100 people across offices in the UK and America, by the middle of 2015.

The private equity group bought The Foundry in 2011, at which point the company was predicted to be worth about £75m.
