In the title compound, C 27 H 20 BrNO 3 , the pyrrolidine ring adopts a half-chair conformation, while the other five-membered rings adopt flattened envelope conformations with the spiro C atoms as the flap atoms. An intra­molecular C—H⋯O hydrogen bond occurs, generating an  S (6) ring. In the crystal, mol­ecules are connected  via  weak C—H⋯O hydrogen bonds, forming chains along the  c  axis.

4′-(4-Bromophenyl)-1′-methyldispiro[indan-2,2′-pyrrolidine-3′,2′′-indan]-1,3,1′′-trione
