The Monster X Strikes Back: Attack the G8 Summit (2008)

When heads of state gather at the G8 summit in Japan, Guilala -- the intergalactic monster that had been banished from the earth in The X from Outer Space -- returns to ravage the Japanese countryside and threaten the world leaders. Military strikes prove futile against the beast, but a reporter learns that one rural community possesses a strange ritual that might influence the creature. Minoru Kawasaki directs this campy satire.

Unfortunately the movie The Monster X Strikes Back: Attack the G8 Summit is not yet available on HBO Max.
