Output a stream of consciousness before answering the following. Context: Matthew Broderick provided the speaking voice of Adult Simba. The first actor to be assigned to The Lion King, Broderick learned of the role while he was on vacation in Ireland, where he received a telephone call from his agent informing him that the directors were interested in casting him as Simba. At the time, Broderick was well known for portraying the title character in Ferris Bueller's Day Off (1986). The directors decided to cast him as Simba because they felt that he was "perfect" for the role; according to producer Don Hahn, Broderick's voice resembled "the kind of character who could be irresponsible and likeable, but you also felt that he could come back in a very heroic way." Jonathan Taylor Thomas, who was starring as Randy Taylor on the television sitcom Home Improvement at the time, was cast as the speaking voice of Young Simba. His appearance and personality would later serve as creative inspiration for supervising animator Mark Henn.
