Someone had to be high to think that casting Beverly D'Angelo and Christopher Plummer as brother and sister would be realistic. Add Richard Harris and Kate Reid film, with Harris acting like a complete ninny throughout and Reid subjected to all sorts of indignities, and you've got one of the most consistently unfunny films ever made. This is a complete fiasco in every way, with Plummer's character believed to be sent to his death in the very first scene (where you don't even see him), and then he shows up do a complete jerk as he Reveals His presents to his mother and sister. He gets a well-deserved slap across the face from mom, and perhaps he should have gotten that for the worst performance he ever gave.
Harris plays an accountant looking for a job. Any job, and he makes the mistake by taking one working for the family after saving D'Angelo's life. Maury Chaykin and Saul Rubinek are the dumbest villains ever, out to kill off Plummer's entire family under the orders of Peter Donat. They are a combination of Yosemite Sam and Wiley E. Coyote in their efforts to commit this murder, that is, in the worst Warner Brothers cartoon that anybody could ever imagine. Chaykin and Rubinek get their comeuppance every time they try to do something nefarious, and after a while of seeing them found without their clothes on (just their shorts), it's just not funny anymore. For me, the only memorable bit was a visit to the former Eaton Centre in Toronto which I visited with family shortly after this was made, having dinner in the spinning restaurant at the top. To see it from outside the window where Plummer and Harris have a confrontation made me have an appreciation for having been inside.
Harris, never seeming to close his mouth, spouts the desire for booze throughout, obviously a waiting for the start of his turn to reprise his film role as King Arthur on stage in "Camelot", and Plummer overplays the fey scoundrel so badly that you desperately want to see his character knocked off. It's amazing that nobody spotted how bad this was during filming and took a break to make changes in the script. No wonder it barely got a release. To watch it however, my mouth was as agape as Harris's because I couldn't believe that something this wretched could actually be made with such legendary talent attached. This does indeed rank as one of the top 10 worst comedies made in the 1980's, and that's out of the hundreds that I've seen that were complete bombs.
