Toru Iwatani: An arcade repairman. The creator of Pac-Man (1980) did not play himself because he doesn't speak English.

Several of the game figures that the aliens use for their patterns are from games released after 1982, such as Tetris (1984), Arkanoid (1986), and Paperboy (1984). The film never claimed that the probe was launched in 1982, only that it included footage from that year. It could've been launched years later, and included footage from later years. Long delays aren't that rare in NASA. Also, the aliens could've updated their data by picking up Earth transmissions after the probe got their attention.

The closing credits re-run a synopsis of the movie in 8-bit style.

According to Reuters and other news sources, the film was censored to increase the chances of being releases in the Peoples' Republic of China (China only allows a total of 34 foreign films into the country) and to increase revenue. In the original 2013 script, the aliens blasted a hole in the Great Wall. That scene was deleted and instead, the aliens struck iconic sites elsewhere, smashing the Taj Mahal in India, the Washington Monument and parts of Manhattan. This new version became the worldwide release, not just an alternative.
