The lead actors, great theatrical geniuses both, convey an absolute disinterest in their roles and only put forward what their particular personas can convey in this. Though the adaptation makes more sense than the original film, the actors are just walking through their parts to make a few bucks as compared to the care Finney and Courtenay put in their roles in the original. Of course, considering their talents I was impressed by their expected competence -- but watch the original to see better performances.
