He made his first appearance at Drury Lane on 1 October 1827 as Norval in Home's Douglas, but his continued failure to achieve popularity led him to leave London in the spring of 1828 for the provinces.

In January 1838, however, he returned to Drury Lane, and played Hamlet with a success which gave him a place among the principal tragedians of his time.
