“An Instant” (Un instante, Spain, 2017, 19 min, directed by Adria Guxens).
A scholarly boy Hugo(Andrian Sanchez-Campo), riding the train and once in a while trying things, meets rock singer Cosmo (Marc Joy) in a bar. Cosmo is much more daring, with tattoos and nose rings and chain smoking.
Whatever superficial disapproval, Hugo becomes attached to him, until he takes leave again, in a series of platonic encounters.
This short was in many festivals.
