OK, they may not all be bisexual all the way through, but these movies take place during Thanksgiving and have at least one hysterical or poignant bisexual moment in them.

* Home For The Holidays
     Robert Downey Jr. is charming as a prankster who comes home for Thanksgiving and tries to come out of the closet by bringing home a hunky friend (Dylan McDermott), but none of his family wants to acknowledge his same-sex attractions. His sister (played by Holly Hunter) has a bad head-cold, and her daughter (Claire Danes) announces that she wants to lose her virginity that weekend. Jodie Foster directed this dysfunctional and funny family situation.

* Brokeback Mountain
     The Oscar-nominated film has a painful scene of the two lovers, Jack Twist (Jake Gyllenhaal) and Ennis Del Mar (Heath Ledger) spending their Thankgivings fighting with relatives, rather than being together.
    Twist's father-in-law rudely insists on watching football during the turkey carving and he declares that it will "make a man" of his grandson. It gets uncomfortable when Jack turns the TV off and insults his father-in-law. It's very obvious that the two bi cowboys would be better off stuffing their turkeys together.

* The Daytrippers
     This odd little indie film mostly takes place in a car packed with great actors like Anne Meara, Parker Posey, Liev Schreiber and others in a story that follows actress Hope Davis in a search for her husband, played by Stanley Tucci. It's just after Thanksgiving when the hapless housewife finds a love letter written to her husband, who is suddenly missing.
     Unfortunately, to reveal that this funny family movie is bisexual actually will ruin the film for anyone who wants to see it.

* Love Actually
    This mosaic of individual stories all takes place in the period of time between Thanksgiving and Christmas, but the best one is with actor Kris Marshall as Colin Frissell. An English slacker, he arrives during the holidays in Milwaukee with a backpack full of condoms. Somehow, he stumbles across a cute blonde bombshell who has a few roommates who are all bisexual. They also sleep nude, and they take a fancy to the Englishman.

* Planes, Trains and Automobiles
    You've got to admit, it was brilliant casting putting these two wild and crazy funny guys together. Steve Martin and John Candy co-star in this 1987 classic by John Hughes about an advertising executive who wants to fly home to spend Thanksgiving with his family but instead gets stuck with a loud salesman because of blizzards, strikes, transfers and delays.
     No, the guys don't turn bi, although they end up becoming bosom buddies by the end, even though they hate each other along the way. But, one of the most hysterical moments in the movie is when Martin has his hand tucked between two pillows when the guys have to share a bed, but then his bunkmate Candy screams, "Those aren't pillows!"
