Marcel the Shell with Shoes On

A one-inch shell lives with his grandmother in an Airbnb, and a documentary about them becomes a way to look for the rest of the family. Fleischer Camp keeps the scale literal: a tennis ball is a car. Jenny Slate voices Marcel as curious and exact. Isabella Rossellini’s Connie is the one who may not see the end of the search. The A24 trailer is the shoe and the window. The film is gentle about fame and serious about who is missing.
