It's a bit confusing... I find DVD's with runtime 105 minutes, but apparently there's also a longer version, 130 minutes. Would that longer version per chance be a directors cut? Anybody knows if the longer version (which has to be imported from USA, I'm European) is so much better than the regular 105 mins version?
shareThe only version of the film I’ve ever seen runs just about an hour 45 minutes. My suspicion, however, is that the longer versions you’re encountering might be video recordings of the radio performances, which are also available. See for example http://www.amazon.com/Prairie-Companion-Garrison-Anniversary-Celebrati on/dp/B00065GHO2/ref=pd_bxgy_mov_text_y It doesn’t run over 2 hours as does the version you mention, but is close.
In essence, they’re two different beasts. The Altman film (at 105 minutes) is the one you want. Hope this helps!
