Movies with same director
One comment referred to 'Jack's Back' (1988) with the same director/writer. Like 'The Stickup' it gave James Spader the chance to do what he does so well -make you wonder just what the character will do next and whether or not he's on the side of the angels.
Spader was in another Rowdy Herrington movie in 2003, "I Witness", though this time he wasn't the lead and Herrington didn't write it. Again the character was enigmatic - I wasn't sure until almost the final reel whether he would turn out to be the baddie.
