Apparently no one has mentioned the reciprocity error (Schwarzschild effect) when measuring for film, and it's probably the only things OP should be concerned about.

You see, the response of the digital sensors was designed from the film response in the 1/10000 - 1" range, which was applied lineally to the rest of the range.

In digital, to get an extra stop you just multiply your exposure time by two, and that is true for any given range (the maximum most cameras work with is 30", but this rule applies for longer ones). The response is linear.

But in film this 'linear' approach only works as an approximation in a very small range (The previously mentioned 1/10000 - 1"). The response is NOT linear AT ALL, and it depends a lot on the film you are using (Refer to the datasheets for more information). Let me explain this with a handy chart you will be using a lot (It was taken down from flickr but I treasure a copy in all of my thumb drives just in case):

As you can see, once you pass the 1 second mark, things get wild. If you measure something with your digital camera and decide that 10" is OK, it will be OK in digital. In fact it will probably look OK in any digital camera you get your hands on.

If you try to take that photo on film with the same parameters, it will look... Well, very bad. If, for example, you are shooting Tri-X (Why would you shoot with any other thing?), you need to add 2+1/3 stops to that time to get the same exposure. That is, 10"*2*2 (40 seconds) +1/3, which total around 50 seconds.

You can see how different the times can be for not-so-long exposures. I'm not going to go through why this happens, you have plenty of info on that pretty much everywhere (Any serious book on film will cover it, I always recommend the Ansel Adams trilogy for anything film-related).

The same thing happens when you shoot faster than 1/10000. The film does not behave in a linear manner and you should correct for this effect.

Other than that, measuring for film is the same as measuring for digital, and you get the same effects modifying the same parameters (Depth of field, motion blur, etc), with the only exception that you get more grain instead of digital noise when pushing film or shooting with sensible emulsions.
