There's a super controversy brewing around this year's Supanova expos, with thousands of pop culture fans threatening to boycott the events if planned appearances by actor Adam Baldwin go ahead.

More than 4,000 people have signed a petition calling on event organisers to revoke Baldwin's invitation to the Sydney and Perth events over his promotion of the GamerGate movement.

Baldwin rose to fame as the trigger-happy sergeant "Animal Mother" in Stanley Kubrick's 1987 classic Full Metal Jacket.
