Meanwhile, in København Matt Helm’s Lincoln Continental Mark III in København, in The Wrecking Crew. Unfortunately for Dean Martin, Sharon Tate and the cast, there’s no evidence of them ever setting foot in Europe for this ﬁlm. Some second-unit actor had to don a Dino wig, a lot, and act drunk.
I can’t ﬁnd much on ﬁlming locations on the web for The Wrecking Crew. While there are obvious Californian locations, such as Palm Springs, doubling for Europe, the train heist, which could have been ﬁlmed in the US, appears to have been done on the Continent.
There are various details about these train scenes in the vehicles that betray the fact they are not Stateside.
