The Witch bgt audition

Britain's Got Talent viewers were terrified by mysterious act The Witch on Saturday, but some think a star could be masquerading as the character.

Others suggested that the act reminded them of something he would produce, with one saying: "Reminds me of a Mark Gatiss creation." Another commented in response to the speculation: "I thought exactly the same." Whilst one viewer asked: "Is the Witch Mark Gatiss from [the Doctor Who episode] #TheLazarusExperiment?" One fan asked: "I wonder if the Witch really is Marc Spellman in costume?" "I was thinking Stephen Mulhern in disguise," speculated one fan recently. The sentiment was shared by others on the social media platform. Another asked: "Anyone else think the Witch is Marc Spelmann?" They said it could be his third attempt at BGT. Others have suggested it could be Stephen Mulhern, 45, behind the act. "Definitely Ant or Dec in costume," wrote one fan following the audition. I thought it instantly." A number of viewers speculated that it could in fact be magician Marc Spelmann, 49, underneath the prosthetics. Viewers immediately theorised that it was Declan Donnelly, 46, behind the act.
