A polymerizable composition includes a polymerizable liquid crystal compound of Formula (I) and a urethane (meth)acrylate monomer including a urethane bond and three or more (meth)acryloyl groups: Q1-Sp1A-Lm-1A-Sp2-Q2  (I) In Formula (I), A represents a cyclic divalent group (at least one is a divalent saturated hydrocarbon ring group), L preferably represents —C(═O)O— or —OC(═O)—, m represents 3 to 12, Sp1 and Sp2 preferably are alkylene, and any one of Q1 and Q2 represents a polymerizable group. A film including a layer obtained by curing the polymerizable composition; and a film adjacently including a layer obtained by curing the polymerizable composition including a polymerizable liquid crystal compound represented by Formula (I) and a layer obtained by curing a composition including a urethane (meth)acrylate monomer and a manufacturing method thereof, are also disclosed. The polymerizable composition includes a polymerizable liquid crystal compound having low birefringence and provides a highly durable optical film.
