I happen to stumbled upon this apparently 2 years late but I needed the answer and after paying around for a bit and googleing I figured It out. I thought it would be nice to post the answer for future reference.
My solution was to use a cube setup as film roll straight. Then use a spline warp(mograph) to warp it with a spline. I originally tried like like Paul Maynard but texture would not come out right unless it was straight. Which is ok but chances our you need the film to roll and bank. But this way with cube projection on UVW Mapping and warping the whole object(I think) there is no issue of distortions on the texture.
Below is what I made to figure it out. There’s a bunch of tuts now for spline warp
