Question: I want to do a photo shoot using film, but due to not being able to see the shots I've taken I would first like to take a digital photo, then recreate it using film.

If I used the same focal length, ISO, aperture size and shutter speed, would the photo was taken digitally be exposed the same as the film photo? Maybe crop vs non crop sensor may affect things?

If not, what can I do to achieve similar levels of exposure (I don't just want to rely on the film cameras light meter all the time)?

Answer: 
There should be no problem trusting the exposure meter built into the camera. Film has exposure latitude that digital (still) does not. So even if exposure is not spot on, it can be adjusted in post. This is probably bad form, but because of film latitude, it's possible to meter once and use the same exposure setting throughout a shoot, as long as lighting doesn't change significantly. This is basically how disposable cameras operate as well.

There are scenes that film cameras are more likely to have difficulty metering than digital cameras. If the camera misjudges by only a few stops, film latitude should be sufficient. Otherwise, you can use exposure compensation or exposure bracketing.

*Note:* When I write, "same exposure setting", I do not mean that ISO, shutter speed, and aperture have to stay the same. Rather, the settings can be adjusted with respect to each other to keep exposure "constant" without referring back to the meter.

The idea is to think of balancing a math equation in terms of "stops". If one setting goes up a stop, another setting has to go down. For shutter speed and ISO, multiply and divide by 2. For aperture, the stops are at 1.4, 2.0, 2.8, 3.5, 4.0, 5.6, 8.0, 11, 16, 22. There are exceptions and further details, but this is good enough for the typical case.

Personally, I'd use aperture priority and trust the built-in meter. I have a bunch of nice pictures that were taken with a film camera that provided only a programmed auto exposure mode that could be kicked into aperture priority if desired.
A “good” exposure is defined as that that amount of light energy that produces an image with satisfactory tonalities and color characteristics. To allow repeated and duplicated results, the industry has standardized the ingredients of the exposure. 1. Scene brightness (Lux or Lumen level) as measured by photographic light meter system. 2. Sensitivity to light of film or digital sensor (ISO). 3. Shutter speed (accurate timing apparatus). 4. Capability of the lens to gather and transfer light (f-number).

Given the standardization there remain numerous pitfalls. The accuracy of brightness measurements are a variable based on the truthfulness of the instrument and the procedure performed by the user. The sensitivity of film is well regulated by the International Standards Organization, digital sensors only loosely follow these guidelines. Modern shutters are quite accurate, nevertheless there will be errors. The f-numbers are a ratio that equalizes all lenses, regardless of their dimensions. However this system is slightly flawed because the f-number does not take into account light absorption with the system. 

Nevertheless, you can count on a reasonable like rendering of the subject provided the cameras are set to the same equivalent exposure. The differences encountered are facts of life. No two pictures taken with different cameras will be exactly alike. The difference is likely minuscule however when we compare film and digital there will are dissimilarities inherent to between the various medias.
