I bought a movie camera last year that had with it a unexposed roll of Kodachrome 25 with it. I only realized recently that I should take a look at it and the possibility of using it after I sold the camera I got it with and bought an older, nicer Cine Kodak. It has an expiry date of November 78 and was stored at room temp since then in a camera bag in its original box and tin. I could tolerate some shift but would it be too far gone? Just thought I'd give it a shot. Maybe give it 1/2 stop overexposure to counteract speed toss It also has the original price tag on it, $3.09 at Drug Fair. Seems like that was an awful lot.
