Lea Seydoux has been offered a role alongside Channing Tatum in the 'X-Men' spin-off 'Gambit'.

The 30-year-old actress - who's also set to appear in the new James Bond movie 'Spectre' - appears to have secured the coveted role of Belladonna Boudreaux in the Rupert Wyatt-directed movie.

Lea overcame stiff competition for the part from the likes of 'Mad Max: Fury Road' star Abbey Lee and Rebecca Ferguson of 'Mission: Impossible - Rogue Nation' to be offered the role, Deadline reports.

This comes shortly after Lea described her casting in 'Spectre' as a ''dream'' and revealed she held a meeting with director Sam Mendes that saw her secure the part.

She recalled: ''Sam invited me for lunch and said, 'Do you want to be part of the film?' And I said yes.

''But for me it wasn't really real. I felt I was in a dream. So I was, 'Yeah ... I mean, yes'.''

What's more, Lea claimed to be in the dark about certain aspects of the film's plot, which remains a closely-guarded secret.

Asked whether she can reveal anything about the movie, she said: ''I like that it's a question. They'll see, you'll see. I mean, even me I haven't seen anything.''
