When I Will Become a Giant (Russian: Когда я стану великаном, romanized: Kogda ya stanu velikanom) is a 1979 Soviet romance film directed by Inna Tumanyan.

[1] The main character, eighth-grader Petya Kopeikin, a self-proclaimed "troublemaker" as his teacher describes, disrupts the school play Cyrano de Bergerac out of dislike for his classmate Fedya Lastochkin, a show-off chosen to play Cyrano.

Petya, an unassuming boy frustrated by his short stature but always at the center of attention, is secretly in love with his classmate Masha Goroshkina.

Masha is charmed, believing Kristallov is both a poet and a "renaissance man" (he’s also a basketball player).

She recognizes Petya’s sincere affection and noble actions, while seeing Kristallov for what he really is—an empty shell.
