Planning our first short film

Our task was to film and edit a character opening a door, crossing a room and sitting down in a chair opposite another character, with whom she/he then exchanges a couple of lines of dialogue. Our short film must obide the 180 degree rule and include a match on action shot and a shot/reverse shot.
To start, we drew up a story board to plan what different shots we would use, plan the action within each shot and think out our dialogue. This was done on an A3 sheet to allow us to plan 8 different shots.
Our idea was to have a close up shot of a mans face walking up to a door, with an extreme close up of his hand opening the handle. We would then see a mid shot of a girl tied to a chair struggling, to a sudden shot of the first character inside the room. There would then be a point of view shot of the man walking over to the tied up girl, exchanging dialogue with her, before hitting her to end the scene. This idea would then cover the shot /reverse shot and the 180 degree rule by flicking from one person to the next while they speak, only using one side of them to film. Also, it would use the match on action of the character going towards the door then suddenly being inside the room.
