Ideas and advice

Some excellent films which use surveillance as a theme:

Rear Window (Hitchcock’s masterpiece) or Disturbia (the remake starring Shia LaBeouf) - a man spies on his neighbours and witnesses what might be a murder.

Any spy film (e.g. the James Bond series of films, the Bourne films) - an international spy gets followed by evil corporation and/or CIA

Lost Highway (1997) - a couple receives videotapes recording the outside then the inside of their home

Enemy of the State (1998) - The main character is pursued by the National Security Agency, which uses an array of surveillance technologies.

Panic Room (2002) - A woman and her daughter use closed-circuit television to follow the movements of criminals invading their home.

Vacancy (2007) - A couple staying at a motel begin watching low-budget horror movies available on tape and realize the movies were filmed in their own motel room.

 

The Conversation (1974) A surveillance expert is hired to combine wiretapped recordings of a couple and tries to interpret their conversations.
