The ghosts of actor Charles Macklin and clown Joseph Grimaldi are also supposed to haunt the theatre. Macklin appears backstage, wandering the corridor which now stands in the spot where, in 1735, he killed fellow actor Thomas Hallam in an argument over a wig ("Goddamn you for a blackguard, scrub, rascal!" he shouted, thrusting a cane into Hallam's face and piercing his left eye). Grimaldi is reported to be a helpful apparition, purportedly guiding nervous actors skilfully about the stage on more than one occasion. The comedian Stanley Lupino claimed to have seen the ghost of Dan Leno in a dressing room.
