Glad to see Lambert mentioned! Here's a photo I found which shows him a bit more in a 1950 matinee idol glossy mag look.
Whilst born French, he's completely bilingual and works both in America, England and France in theatre, cinema, tv and recording artist. This site (in French) gives the breadth of his career across all these disciplines:
Lambert Wilson
My fave is that 2 years ago he starred in Paris in a brilliant remounting by Canadian Robert Carsen of Bernstein's 'Candide' in which he plays 'Voltaire'/'Pangloss' and a 3rd character 'Martin'.
And while looking for some info, found a little-known fact that he had a role in the 1977 film 'Julia' with Jane Fonda and Vanessa Redgrave.
