Not sure if these ones have already been posted but you can find them all on Fightnews....here's the link:

Out of the four guys who are all weighing in at 140 I reckon that Hatton does look like the thinnest of the lot, and then Castillo. But I guess that tends to mean they are the best at that weight, because of reach and strength, unless they have to be too watered down to make the wieght.
Anyhow....have a look at the bottom picture, and see whether you see the comparison between MAtty Hatton's opponent, and this chap from City Slickers.
