Tom Hooper really pushed finishing the Cats movie to the wire, then.
The director told reporters at the film's premiere in New York last night, that he'd put the final touches to the musical at 8am the previous morning, following a non-stop 36-hour push.
Asked whether he was happy with how the film's visuals had turned out, he told Variety on the red carpet: “Yeah, I finished it at 8am yesterday after 36 hours in a row putting the finishing touches on.

“So I'm very happy to be here with it fully finished. We'll let the audience decide, but I think we've come a long way since out first trailer.”
The comment clearly related to the early, erm, 'interest' in how the first trailer looked, which went thoroughly viral.

Movie fans relished the social media scrum to brand the first visuals 'a demented dream ballet', as stars from Judi Dench to Idris Elba were transformed into cats for the Andrew Lloyd Webber adaptation.
But now people have seen the movie, there are dribs and drabs of reaction coming in on Twitter ahead of the full reviews.
And it feels like the (very recently) finished product is every bit as hallucinatory as we'd anticipated.
The star-laden movie – which features Dench and Elba alongside James Corden, Jason Derulo, Jennifer Hudson, Ian McKellen, Taylor Swift, Rebel Wilson and Royal Ballet star Francesca Hayward in the lead – tells the story of the tribe of cats known as the 'jellicles', lifted by Lloyd Webber from T.S. Eliot's Old Possum's Book of Practical Cats.
It lands in the UK on December 20.
