Well, with enough effort it is possible to build a system that is more
useful than "entertaining". Google did that, English youtube videos can
be annotated with subtitles from speech recognition. For example, try
this video:

There's not much background noise there; it takes place in a quiet room.
It becomes a bit worse once the background music sets in, but still is
usable. Feel free to try any other video. I think, it works with any
video in English.
I think that for "Hollywood"-style movies you will always have a crisp
sound of the speech. They want the viewers to listen effortlessly -
background music is typical, "true" noise is rare.
Maybe try with this video:

As soon as they are up in the air you have the engine sound overlaying
the speech, and still the transcription is quite good. It sometimes
mistakes the flapping of the engine as "applause" and misses a word or a
sentence, but still very good.
