"Dead Heat on a Merry-Go-Round" is probably mostly of interest to us nowadays due to Harrison Ford's bit part as a bellhop. Apparently, after the movie bombed, a producer told Ford: "Kid, you ain't got it." Of course, Ford went on to star in the "Star Wars" and "Indiana Jones" trilogies, so he clearly had lots of "it".
Anyway, the movie casts James Coburn as ex-con Eli Kotch, plotting a heist in LAX while the Russian prime minister is visiting. Coburn seems to be mirroring his Derek Flint character, right down to being surrounded by hot babes (specifically Camilla Sparv and Nina Wayne). The good ol' Cold War, when the US and USSR could play all sorts of tricks on each other, and there were plenty of beauties to go around.
Overall, "DHOAMGR" isn't a great movie, but it's worth seeing. You may notice that playing Mrs. Kirby is Rose Marie, better known as Sally on "The Dick Van Dyke Show".
Nina Wayne. Hubba hubba...
