How long does undeveloped film last?

Question

I received a Mamiya ZE-2 from a family member who discovered it in a closet. Along with the camera were 3 rolls of film - 2 in white plastic holders and one inside the camera.

I have no idea what may be on the film, but they seem to have been used (not developed). Would it be worth it to go develop them, will they still have the photos on them?

The 2 rolls in casings are Fujifilm Superia 400.

Answer

This depends totally on the conditions it is kept. The date on the film tends to be a conservative figure and as long as it's been kept cool it tends to last a lot longer than this. If the film is years out of date you have to make a decision if you want to risk it because you may end up with nothing.
