Colin Baker (born 8 June 1943) is an English actor and was the sixth Doctor Who. He played the role from 1984 – 1986, starring in 31 episodes over 3 series.
Baker joined Doctor Who in 1984, though he had appeared in the role of Commander Maxil in the Doctor Who story Arc of infinity (1983) before he got the starring role. He was later replaced by Sylvester McCoy, but due to falling out with the BBC, Baker did not do the regeneration scene, which is something he would later regret.
In 2011, Baker accepted the presidency of the Doctor Who Appreciation Society after winning more votes than all the other candidates combined.
