After her showing in the beauty contest, she was given an audition by Paramount Pictures and cast by director Herbert Brenon as Wendy Darling in his silent movie version of J. M. Barrie's Peter Pan (1924).
There she starred with Betty Bronson and Esther Ralston, and the three of them stayed close for the rest of their lives.
Ralston described both Bronson and Brian as 'very charming people'.

The studio, who created her stage name for the movie and said she was age 16 instead of 18, because the latter sounded too old for the role, then signed her to a long-term motion picture contract.
Brian played Fancy Vanhern, daughter of Percy Marmont, in Brenon's The Street of Forgotten Men (1925), which had newcomer Louise Brooks in an uncredited debut role as a moll.
