Initial Full Film Idea + Synopsis

• My film is a comedy thriller
• There are two main actors a male and female
• The two main characters are boyfriend and girlfriend
• Without any indication as to why, the couples bodies swap
• The two are desperate to switch back and aim to find out why whilst living as each other
• Amusing things happen whilst in each others bodies- this idea is mainly inspired by Freaky Friday
• However the boyfriend, who is in the younger girlfriend's body, wants to stay in her body to have a new life 
• Instead of working together, the girl (in her boyfriend's body) has to work alone to switch back into her body-this is where the thriller elements come in which is inspired by scenes from Heathers 
• At the end Kat isn't able to find out what switched them. In a dramatic talk with Kris they agree on hopefully waiting to be able to switch back. Kat is left unhappy and the film ends on a cliffhanger

This is my initial full film plan idea. Of course, the last scenes will not be in the trailer but these bullet points help to give me key scenes that I will include. I've including in this list some films that are not comedy thrillers but are of either genre so will inspire some scenes and ideas.

Next I will think of scenes and create an order for my trailer.

Synopsis

Katherine and Kristian were a happy 18 and 20 year old couple.  Katherine goes to collage whilst Kristian is unemployed. With no indication as to how or why, the couple’s bodies swap. At first, the couple find this amusing and play around with each other’s bodies whilst also being freaked out. They agree that they'll live as each other until they find out how to change back. Whilst living as each other they discover things about their friends such as secrets- including Kris's friend admits to him (whilst in Kat's body) that he likes her. At other points whilst Kris is at school in Kat's body her friends seem confused by 'her' behaviour. Kristian also slacks when it comes to doing Kat's work which causes her grades to go down since he doesn't understand her subjects. Whilst Kat is in Kris's body his friends argue with her and she becomes distressed. At this point the couple have made no progress and Kat discovers that Kris wants to stay in her body. Kat has to work alone to win her body back and will go to any length to do so. At this point Kristian is enjoying his new life as Kat and uses the switch to mess with her life by drinking and gambling. Kat and Kristian end up fighting and hit each other comically, Kat in Kris's body is alarmed to have hurt her own face as Kristian in Kat's body wails as he didn't realise the strength Kat has in his body. However Kat is still annoyed at Kristian and threatens with a knife to kill her own body saying that if she can't have her life back then no one can have it.

Being a comedy thriller like Seven Psychopaths, I felt it would make more sense to leave the film on an unexpected cliffhanger which will distress audiences, putting them in the same mood at Kat would be and leaving them to assume their would maybe be a sequel. This is also inspired by SightSeers which ends with the girlfriend killing the boyfriend which was highly unexpected, seeing as the boyfriend seemed like the worse person in comparison.
