It appears the producer of Independence Day and its 2016 sequel, Independence Day: Resurgence, has liberated himself from the idea of doing a third ID4 film.
Emmerich definitely appeared up for a third Independence Day film just prior to Independence Day: Resurgence’s release, even going so far as to say the third film’s setting would be intergalactic.
According to LRM, Devlin was asked about the potential for another Independence Day film while he was at WonderCon in Anaheim, California, over the weekend promoting his new horror thriller Bad Samaritan.
Devlin most certainly has to feel deflated by Independence Day: Resurgence’s reception, which was far less kind than the way the original was received.
