The present invention provides a new polymerizable compound which is represented by Formula (I). In the formula, R1 indicates an alkyl group or the like, A represents a (m+n)valent cyclic group, L1 indicates a single bond or the like, L2 indicates —COO— or the like, Z indicates —COO— or the like, Sp indicates an alkylene group, an alkyleneoxy group, or the like, Q indicates a polymerizable group such as a (meth)acryloyl groups, 1 indicates an integer of 0 to 2, m indicates an integer of 1 or 2, and n indicates an integer of 1 to 3. The present invention also provides a polymerizable composition which includes the polymerizable compound described above, a film which is formed from the polymerizable composition described above, and a half mirror for displaying a projection image which includes the film described above. Using the polymerization composition described above, it is possible to manufacture films such as a low birefringence retardation film and a reflection film with high reflection wavelength region selectivity.
