Watched this on the flight to LA yesterday and loved it. as a breif summary:

A man is the cause of his own birth and has to travel back in time and have sex with himself as a woman from the past, giving birth to a child who travels back in time and grows up to become them. The result is a causality loop which takes the ‘chicken or egg’ dilemma to a whole new level

Well worth a watch if you like time travel paradox movies.

Sounds awfully like http://en.wikipedia.org/wiki/All_You_Zombies (here http://cla.calpoly.edu/~lcall/303/heinlein_all_you_zombies.pdf if you want to read it).

Good to see the film-makers have moved on in the fifty-odd years since he wrote it!

I think we can assume its based on that story Neil

It is definitely worth a watch if thats your thing, it is mine and i really enjoyed it, it gets some good reviews too.

Reverse time-travel is logically incoherent, but not to worry! Sounds fun.

Doesn't seem to be showing round here yet.

It’s a cracking film. I caught it during a film festival last year.

Yes, it’s based on All You Zombies – but if you don’t know the old story, don’t read it until after seeing the film! Predestination works much better when you have no idea what to expect.

I see, it's a last-year film not a this-year film. Will have to wait until it's on the box, then.

No, no … it was screened at some film festivals last year, then got a proper general release just last month. So it’s a this-year film really. I just saw it early!

Cryptic, Trappy, cryptic!

Saw this last year and quite liked it, the acting and photography were excellent but something about the time travel paradox of the story didn't work for me. Maybe I was just distracted by the main character looking a bit too much like Leonardo DiCaprio's evil twin.

Still prefer the Spanish time travel thriller, Timecrimes (Los cronocrímenes).

I saw this next year.

He has nothing to say!

Pace was too slow for my liking and the fizzle bomber sub-plot was weak.
@Graham - Would you agree other time paradox movies usually have more credibility because it's conceivable events in an original timeline led to the paradox existing?

The bomber sub-plot was one of the things invented by the film - it wasn’t part of the original short story. Possibly why it didn’t sit so well?

If you want a truly cracking time travel paradox film, I recommend Primer. Be prepared to watch it more than once though, to try and make sense of the time loops …

But the fizzle bomber was...... because they were all.....

I cant say much without spoiling the film, i quite liked the fizzle bomber plot although the name fizzle was weak.
