I remember seeing it with my dad and having this conversation afterwards:
Me: Did you like it?
Him: Yeah, although it was quite unrealistic.
Me: You mean the part where they use the wormhole?
Him: Nah, the part where they burn the green corn-fields. If it's green it contains too much water to burn.
Interstellar is being shown on television right now - FX HD channel, and will be shown again tomorrow at 5pm PST same channel, and also throughout the week. This is to my knowledge, the first time Interstellar has been shown on network TV.
Interesting to see how the TV broadcast has the whole frame filled in, regardless of IMAX, 35 mm, and the Dust Bowl interview parts - the entire screen is filled in for the TV broadcast. Also, the video and sound seem to be compressed - lots of blotchy noise in the dark areas like the space shots, etc.
