Episodes of Blake Edwards' late 1950s TV series Peter Gunn are available on DVD, and for fans of film noir and/or natty dressing they are indispensable.
Craig Stevens does a passable Cary Grant imitation, both in style and manner, and the series is beautifully shot. Lots of secondhand smoke and jazz lingo.
Stevens was wearing a buttondown collar with French cuffs in the second episode I watched. Made it look good, too.
