 Anthony, along with brother Tyler, were announced as new characters in May 2011, played by Lapinskas and Discipline respectively, although Tyler made his debut at an earlier date. Described as someone who "will rely on his brains and natural wit to find a more sensitive solution to any conflict", it is found out that Anthony has a gambling problem before his character arrived in Walford, which is later a focus of one of the storylines. Lapinskas said of his relationship with half-brother Michael that Anthony "idolises" him, and that Michael "corrupted" Anthony. When Eddie leaves, Anthony takes charge of his antiques business. Executive producer Bryan Kirkwood said that the Moon brothers would bring a new element to the show. Inside Soap held a poll to see which of the new Moon family members, Eddie, Tyler or Anthony, its readers were most looking forward to seeing; Anthony came third with 12 per cent of the vote. Lapinskas quit the show in May 2012. He left EastEnders on 30 August 2012.
