I came across Dead Heat on a Merry-Go-Round (1966) late one night and missed the first half hour or so, which was a pity. Don't miss it if you are a student of 1960s design and style or a fan of the lanky and accomplished James Coburn. He's a smoother, more rugged version of Jimmy Stewart with less of the "aww, shucks" affect of the latter. Coburn plays a clever con man who has a con for everyone including the gals he runs into.
In the film, you'll see examples of the following: a Western suit (see above), corduroy trousers, a grey suit contrasted and paired with an indigo blue oxford cloth buttondown, an astrakhan collar car coat and 3 piece suits with shallow vents. You'll also find period waitress uniforms and TWA stewardess uniforms.
Below is a YouTube tribute to one of the actresses in the film, Camilla Sparv, who gets tangled up with the elusive Coburn.
Coburn starred in other films such as Duffy (1968) and Our Man Flint (1967), a take on the James Bond franchise.
