Long exposure star trail imaging is still an advantage of film. Although methods for DSLR cameras exist, no software stitching is required with film. Expose as little or as long as you like and don't worry about chromatic noise or amplifier glow.
The image here was taken with Kodak Ektachrome 200 Professional film at an aperture of f/8 for a little over 30 minutes. The first quarter Moon illuminates the landscape.
Other films that would work equally well that are available today are Fuji Provia 100F, Kodak E100, and for Black and white work, Fuji Acros 100.
