Just Super had its world premiere on 10 September 2022 at TIFF Junior, a children's film festival held in Tromsø, Norway, where it won the audience award.

It said, "In this film, the white heroes turn into lions that, unlike lions, have dark brown hands and partially dark brown faces and bodies which, as our colleagues pointed out, are depictions rooted in colonial thinking where Black people historically have been dehumanised and compared to animals", and while it "is not a watchdog" but "exist[s] inside the industry and merely identif[ies] problems and the systems that support them", it "wanted to avoid further harm to BIPOC audiences" and that the organisation and its members "received abhorrent emails and offensive remarks" during this process.

[4] Sivertsen explained that the mask and gloves were part of a costume meant to conceal the hero's identity and that the lion was chosen because it was featured in the logo of the Norwegian Automobile Federation, the film's main collaboration partner, and in the coat of arms of Norway, and because it is "a well-known symbol of courage and strength".

It said after "numerous meetings" the Berlinale asked the producer and the NFI to consider withdrawing the film from the festival, which they declined, so they "reluctantly" agreed with the cancellation of the premiere.

The letter continued, "We are also concerned that one of the effects of the events at this year's Berlinale, can be that programmers become hesitant to program potentially controversial films in fear of being targeted by activist interest groups.

[11] On 17 April 2023, Schwarze Filmschaffende, a network of Black film artists in German-speaking Europe, issued a public statement condemning the Berlinale's selection of Measures of Men, Seneca – On the Creation of Earthquakes, and Just Super, which it said promote "anti-Black racist images, tropes, stereotypes and discriminatory narrative forms".
