The Lure of Youth (1921)

Florentine Fair, a famous actress who is satiated with theatrical life, falls in love with Roger Dent, an unsophisticated youth with a passion for writing plays. Taking him to New York as her protégé, she encourages him to write. Although her lover Mortimer is insanely jealous at first, he finds merit in Dent's new play and finances him on Broadway.
