- ―Duncan's Driver, All the World's a Stage
The Actor is the owner (and quite often passionate lead performer) of the Sodor Shakespeare Company and its various productions.
In All the World's a Stage, the Actor is performing a play at the Sodor Shakespeare Company's outdoor theatre when Duncan crashes into it. The Actor becomes enraged and insults Duncan. Later, he converses with The Thin Controller and orders that he provide him compensation for the damage caused by Duncan. However, when Bertram steams up and begins reciting Hamlet, the Actor changes his mind and allows the Thin Controller to put on a play with Bertram as director in place of paying him.
