Die Katze auf dem heißen Blechdach
In late 2014, O'Malley appeared as Big Daddy in "Cat on a Hot Tin Roof" at Manchester's Royal Exchange Theatre. O'Malley was nominated as Best Actor at The MTA Theatre Awards - MTA stated "Cat on a Hot Tin Roof seethes with unhappy people circling the central character, patriarch Big Daddy. Daragh O’Malley blisters his way through this famous role like a raging bull with great physical presence tempered by emotional vulnerability". The Times called O'Malley's performance as Big Daddy "towering in every sense of the word".
