Both are in their 80s now, and while Vaughn has done a lot of significant film work in the last 50 years, McCallum remained a TV figure for the greater part of his career. UNCLE is a parody masquerading as a serious spy thriller. Tom Cruise was to play Solo, and the film was earlier to be helmed by a different director. My apologies, nevertheless. The German actor is also a singer, a tenor, and his film appearances include Generation War. He has the basic facial structure of Jack Nicholson, and I guess Ritchie could not resist modelling him as such.
