In the UK it seems, but in the US, there was no impact or awareness at all of this band between New Kids / N'Sync, even among the main teenage girl demographic that could tell you everything about those latter bands but is borderline guaranteed in the US to never once have heard of Take That.
Not that it matters, just underscores how strange it was to make this film on a budget that requires US + world box office sales in order to recoup their loss, but for a film that has no way to succeed in this region since it's a biopic of an unknown.
