Johnny Christopher (Lawrence Tierney) drives a 1941 Ford Station Wagon.
Retakes were often required as a result of Lawrence Tierney's showing too much "enthusiasm" for Anne Jeffreys in his close fitting swim trunks.
Step By Step was also the name of a TV series from the 1990s, and the star of that show, Suzanne Somers was born in 1946 which is the year the movie of the same title came out.
Lawrence Tierney and Anne Jeffreys had also starred together in DILLINGER, that ignited Tierney's career, although this is one of his few good guy roles.
