Very Special Favor (A)

Michel Boullard (Charles Boyer) meets Paul Chadwick (Rock Hudson) while going against him in a court case in France. To win the case, Chadwick woos the attract female judge, and this becomes known to attorney Boullard. After meeting his daughter, Dr. Lauren Boullard (Leslie Caron), a Fredian psychiatrist, whom he hasn't seen in more than 20 years, Boullard discovers she's engaged to a momma's boy named Arnold Plum (Dick Shawn), that she can now boss around just as well as his mother. You see, Lauren is a control freak and her father wants to knock her down a peg or two, so he enlists Chadwick's help to woo her away from Plum.

In return, Boullard will not tell anyone that Chadwick won a court case by wooing the judge. After getting her drunk, Chadwick pretends to sleep with Lauren much to her dismay, and she becomes upset with Chadwick until it happens again. After the second time, Lauren begins to believe she's now in love with Chadwick convinced by her Freudian background that these tendencies are latent in her subconscious. Chadwick in turn, begins to fell like a heal because he is beginning to fall in love with Lauren as well and the two begin to act seriously toward each other. Boullard must break them up before the unthinkable happens, and his daughter loses her virginity to Chadwick while they are still not married, so he tells Lauren what Chadwick did to her to pretend he slept with her.

Now Lauren is really upset and plots to get even with Chadwick by doing the same to him except it backfires, and the two find each other out. Plum is out of the picture as Chadwick and Lauren fall in love for real without any of the shinnanigans.

There was a trailer...but, it has since disappeared.
