just wondering what movies people thought had changed cinema quite alot.

Examples would be Blair witch project which started the shaky cam theme of the 2000s with movies like cloverfield and paranormal activity. ]

Or another example could be a clockwork orange which changed what poeple expected from violence in films.

So what would you say changed movies?

The Matrix. Though I'm not sure all the bullet-timing, camera rotating and acrobatic stuff was for the better of movies in general.

Toy Story... the first feature film to be made entirely with CGI.

and speaking of CGI: Jurassic Park..

gone with the wind

The exorcist

Citizen Kane

Sunset Boulevar

Star wars (original)

Psyhco

many others

these just were the first in mind

cgi wise it should be terminator 2

The Santa Clause.

Hmm.  Think I'll duck this one.  I see recent movie trends and nothing really major noted yet.  Perhaps not the thread for me.

Seven Samurai and The Magnificent Seven. The age old hollywood tradition of stealing ideas and remaking versions of foreign films (that are never as good). There might be an earlier example, but i don't know that much about the history of cinema.

The answer is clear and simple:

STAR WARS
