When i first heard of this i was impressed by it's boldness but more than a little concerned by it's limitations. But with this trailer i think any fears might be put to one side.
I won't bother retelling you the synopsis, the trailer does that. Just watch it and then think of how little you saw and that maybe some of the bigger, more vulgar Michael Bay-esque trailers out there could do with showing a little more restraint and actually teasing an audience rather than trying to bash them over the head to get them through the box office.
Buried is released on October 1st.
