 Many who trained in this medium (such as Peter Finch) subsequently became prominent both in Australia and overseas.It has been noted that the producers of the popular 1960s Gerry Anderson TV series "Thunderbirds" were greatly impressed by the versatility of UK-based Australian actor Ray Barrett, who voiced many roles in Anderson's TV productions.Thanks to his early experience on Australian live radio (where he often played English and American roles), Barrett was considered better than his English counterparts at providing a convincing Mid-Atlantic English ("transatlantic") accent, and he could perform a wide range of character voices; he also impressed the Anderson team with his ability to quickly and easily switch from one voice/accent to another without the sound engineers' having to stop the recording.
