Zimmerman was a late addition to the Thunderbirds cast, having landed the part of Alan Tracy after production work on the first episode Trapped in the Sky was already complete. Yet he went on to become one of the most prominent and best loved characters in the series, taking a leading role in the two subsequent feature films, Thunderbirds Are Go and Thunderbird 6.
As well as numerous other television roles, he has also worked extensively in the theatre, and in recent years has performed in productions of Anything Goes, West Side Story, Fiddler on the Roof and Cabaret.
Zimmerman appeared alongside fellow Thunderbirds voice artist David Graham at the club's last convention, Sector 25, and is very much looking forward to meeting fans again this October.
