Jackie Lane in Tickle Me (1965) by Truus, Bob & Jan too! Via Flickr: Italian postcard by B.F.F. Edit., no. 3566. Photo: Warner Bros. Publicity still for Tickle Me (Norman Taurog, 1965).
Austrian born starlet Jackie Lane (1937) was a stunningly beautiful model and film actress of the 1950s and 1960s, who starred both in European films and in Hollywood pictures. She was married to Prince Alfonso of Hohenlohe-Langenburg.
The real reason that Jackie Lane has not reprised her role as Dodo Chaplet through Big Finish is because she has a strict head canon that Dodo never awoke from the hypnotic trance the Doctor put her in in The War Machines Part 2.
