This is the first feature film live action adaptation of the original Gatchaman animated series from the 1970s.
Most of the footage of this film comes from here.
"Kagaku ninja tai Gatchaman" was edited, censored, and Americanized to become the U.S. TV series "Battle of the Planets."
The boy (Hiroki Iwase) plays with a Gatchaman doll, and later talks about Gatchaman with a policewoman (Shinobu Ootake).
The main characters make a cameo appearance.
When we first see Ben he is wearing a Gatchaman T-shirt.
Ken & Jun make a small cameo in the crowd.
Ken the Eagle & Jun the Swan are playable.
Hewy says Imagi Studios will adapt this show into a movie
