La Cage running time?

Please help! I have room for a Thursday matinee in my forthcoming schedule, but I need to be at the National for 6pm. So I'd lovelovelove to check out the deadly Allam/Quast combo, but if La Cage is longer than War Horse, then I'm probably going to aim safe(ish) and see the ponies again, and save La Cage for another day.

I mean, I've seen it twice already, but I still don't know how long it is. I fail. XD If anyone does know the running time, I'll be very pleased to hear it. :)

Think its about 2 and a half hours, gives you plenty time to get over to the National, only a 5 min walk across the bridge.

Now, Weez you know you can't not see Mr Quast and Mr Allum together!
