Richard Burton's description of the acting profession had convinced him that it would be better than completing his chemistry degree and so Mitchell attended RADA for two years, performing in the evening with London's Unity Theatre.[citation needed] After a short stint as a DJ on Radio Luxembourg, in 1951, Mitchell became a versatile professional actor with straight and comedy roles on stage, radio, film and television. His first broadcast was as a regular on the radio show Educating Archie, and this led to appearances in both the radio and television versions of Hancock's Half Hour.[citation needed]
