They just played The Crowd Roars (the '32 not the '38 movie) on TCM and it was awesome from a car enthusiast perspective. They are doing a whole auto movie night including the 1955 The Fast and The Furious. It has drunkenness talk of defunct brands, real racing at Indy (accidents and open pit lane!!), and talk of tuning all make it especially interesting from a Jalop point of view. Its a pretty good movie with good actors (James Cagney was great).
The only problem is finding it now. Amazon has the DVD but there's no streaming available. I think some DVRs can save a show after the air time? If you get a chance to see it, it is well worth it. Let us know if you find it online somewhere.
