 When the series started, it was not a certainty that  Erin Gray (qv) would sign on to reprise her movie role of Wilma  Deering. As a result, Buck has a few different female sidekicks in  early episodes, notably Juanin Clay (qv) as Major Marla Landers in  the episode #1.5,"Vegas In Space". Clay was intended as a possible  replacement for Gray, until it was decided she would continue in the  series.
