Yes it can be done, but depending on what type of film you're using it can be tricky/impossible. If you're using a film with Pressure Sensitive adhesive you can do it much like a wet vinyl install. Transfer tape it (paper), add a few drops of baby soap or Dawn in a 32 oz squirt bottle, install and wait a few minutes for it to dry a bit, then soak the back of the transfer tape to help it peel easier. Be very careful when pulling the transfer tape off, keep it at 180 degrees.
If you're using film with CDF adhesive (Clear Distortion Free) it isn't tacky like PS adhesive and you won't have any luck unless you're first installing it on a film with PS adhesive and then onto the glass.
