First live action appearance of "Wonder Girl" since February 16 1977
when Debra Winger played sibling Drusilla Troy opposite Lynda Carter's Diana Prince on ABC television's "Wonder Woman".
Back in the 1960's- there was a Saturday morning cartoon on CBS called The Superman/Aquaman Hour of Adventure which was produced by Filmation and aired from 1967 to 1968. Premiering on September 9, 1967, this 60-minute program included a series of six-minute adventures featuring various DC Comics superheroes. One of these six minute segments was called "Teen Titans" and featured Wonder Girl. Hence-Wonder Girl appeared on television before Wonder Woman.
The establishing shot of the train is of a TGV Atlantique.
