Why was David Holliday replaced with Jeremy Wilkin as the voice of Virgil Tracy for the last six episodes of “Thunderbirds”?
The reason for the departure of voice artist David Holliday from the highly-successful “Thunderbirds” prior to the last six episodes of the series seems to be cloaked in mystery. Gerry Anderson says that Holliday asked that his contract be renegotiated between shooting blocks of “Thunderbirds” and wanted too much money and perks. Holliday admits he asked for his contract to be renegotiated but says it was because he was offered better paying work and wanted his duties restructured. In any event, Holliday was released from his contract and actor Jeremy Wilkin (who later went on to provide voices in “Captain Scarlet and the Mysterions”, “Joe 90”, and “The Secret Service” and the Skydiver navigator in “UFO”) took over the role of Virgil Tracy for the final block of “Thunderbirds” episodes and the two classic “Thunderbirds” movies. Holliday went on to making a living primarily as a stage actor, especially in musicals.
