Calum Callaghan is an English actor best known for his recurring role as George Towler, Agnes' brother who shares his sister's strong work ethic and determination to be free of their abusive father, in the period drama television series Mr Selfridge.
London native Callaghan first got into acting when a babysitter put him into dancing lessons while she was waiting for her daughter; a dancing audition led to his first professional gig.
But in 1994, at age eight, he shot to stardom performing with the British boy-band Take That as a mini-version of singer Mark Owen in arenas all over Europe.
From there, he went on to star in numerous musicals on stage in London's West End, including Oliver and Les Misérables.
With the Old Vic New Voices theatre under the artistic directorship of Kevin Spacey, Callaghan has participated in numerous programs and productions; he's also appeared on British television in Torchwood, Silk, and other series.
He was in the 2000 feature film Love, Honor and Obey, starring Jonny Lee Miller and Ray Winstone (Great Expectations).
