Well this listing is outdated, since it's already been nearly six year that Skandar Keynes had claimed to be 5'6".

In this 2008 photo Keynes is a bit leaning, but you can clearly see that William Moseley, who is listed here as 5'9.5" is not much taller than Keynes. We can't see whether they are wearing lifts, but I don't think any one of them has much shoe advantage. I'd say Keynes is around 5'8".
[Editor Rob: the quote is from 06, so yeah it's a bit out of date, he looks from this year near 5ft 8]
