In case you missed our previous release, this is a series of Japanese commercials that star Tommy Lee Jones as an alien investigating Earth. If you read Kotaku, there was an article about this commercial series a couple weeks ago.
Apparently they're still releasing these commercials. I think the last one was just released this year a few months ago.
These commercials are pretty funny on a few levels. Tommy Lee Jones is a great actor, and he plays the alien is totally deadpan. (He has a few speaking lines in Japanese. The lines are very short, of course). At the same time, Jones is also an alien in that he's just a white guy who's surrounded by a bunch of Japanese people.
Spaceman Jones' thought narrations are read by the hauntingly memorable voice of Taniguchi Takashi.
