Restricting browsers to only listed websites

Is there a way to allow a machine on the network to only access a small list of
websites?

I have a fedora 17 machine that is hooked to a tv that I only want to access a couple of
sites for movies. This is accessible to everyone and is only to be used as stated.

I need the network up.

A Cisco router is between the machine and the net that I do not want to reset.
(Unauthorized to do so).

Any help on this would be appreciated.
