Mutt is a 2023 drama film directed, written and produced by Vuk Lungulov-Klotz in his feature directorial debut.

It stars Lío Mehiel, Cole Doman, Alejandro Goic and MiMi Ryder.

In one day, Feña, a trans man, rekindles his relationships with his foreign father, his straight ex-boyfriend and his estranged younger half-sister after having lost touch with them since his gender transitioning.

During the Deadline Studio panel at Sundance Film Festival, Lungulov-Klotz revealed that he wrote the script of Mutt six years prior and recalled the experience as "trying to place all of his fears in the film".

[11] Leslie Felperin of The Hollywood Reporter deemed Mutt as "one of the best films about post-transition adjustment".
