Marcel the Shell with Shoes On is a 2021 American live-action/stop-motion animated mockumentary film, co-written and directed by Dean Fleischer Camp in his feature directorial debut.

It is based on and serves both as a direct stand-alone sequel and prequel to the series of Marcel the Shell shorts written by Jenny Slate and Fleischer Camp.

Following the end of his marriage, documentary filmmaker Dean moves into an Airbnb and discovers Marcel, a one-inch-tall talking shell living in the home with his grandmother, Nana Connie, and Alan, his pet ball of lint.

The shells would take shelter in a sock drawer when the house's previous owners, Mark and Larissa, started knocking objects over while fighting.

Marcel convinces Dean to drive him around the city in search of Mark's car but is overwhelmed to discover how large and vast the world outside his house really is.

Realizing that the world is too big to likely discover the car on his own, a discouraged Marcel returns home to find Connie has fallen off the top of a washing machine and cracked her shell.

Despite Dean's encouragement, Marcel is reluctant to accept the offer, concerned with what the large production crew and more attention to the house would do to Connie's health.

Reunited with his family, Marcel confides to Dean that he often finds himself going to the laundry room window alone and feeling the wind blow through his shell.
