with loads of bad guys and some seriously witty and clever dialog and story telling. "Montana" and "Thick as Thieves". In the latter, Alec Baldwin plays a music collector when he's not doiing capers.
"Thick as Thieves" appears to be a very popular title, it refers to the 1999 movie you mention directed by Scott Sanders based on the novel by Pat Quinn, a 2009 thriller with Morgan Freeman, a 1974 British TV mini series with Bob Hoskins, a 1991 Canadian film featuring Tony Munch, a play, a 1999 pornographic film starring Buddy Jones, an album by Trooper, an album by Kicked in the Head, nine different songs by nine different musical groups, three novels including the aforementioned one by Pat Quinn, and six television episodes, all of the above courtesy of Wiki. Thus it took a few internet clicks to find a review of the comedy in your post.
In any case, sounds like the sly, intelligent humor I like best. My nomination of the genre is "Local Hero" directed by Bill Forsyth, a delightful 1983 Scottish comedy starring Peter Riegert and Burt Lancaster.
