Odd looking Tree

I spotted this tree some weeks ago and thought that looks rather weird; I was able to pull over the car to-day to get a photo despite a fair amount of passing traffic.
I think its covered in Ivy but is surviving looking at the top branches, when I first saw it the sun was shining and it looked even more odd like something out of one of the Harry Potter films! perhaps the one where the car becomes entangled in it and the tree throws the car out?
If you havn't seen the film you won't have a clue what I'm talking about...sorry.

Hope your having a nice weekend.
