Mystery star is escorted out of Bray Studios by security as James Bond screen tests continue after Callum Turner's audition

A Mercedes was escorted out of the Berkshire studios on Saturday afternoon, fuelling speculation that another 007 hopeful had just auditioned. Between three and five actors are understood to have reached the final stage. Callum Turner, 36, went first on Friday. Slow Horses star Jack Lowden remains the bookies' favourite at 4/6, with Turner his nearest challenger at 3/1.

Each screen test is reported to assess three areas: stunts, camera presence and dialogue.

Richard Madden's odds have been slashed from 40/1 to 14/1, which William Hill called a 'huge move'.

Australian Jacob Elordi, 29, is reportedly in the mix, which could anger fans who insist Bond must be British.
