As I recall, there's nothing particular about the type of film one uses for
making holograms (although some extra red sensitivity might be handy). What
you do need, I think, is a high-quality beamsplitter and some front-surface
mirrors. Note that you don't need a camera, although you'll need some
lenses to spread the laser beam.
Hang on a sec', while I do some quick rummaging on the net...

This should show the basics better than I could describe it!
Cheers,

P.S. This just reminded me that I have some old (mid-70s?) science annuals
with some transmission holograms in them. I've goota try viewing them with
that little laser pointer someone gave me not long ago!
