There are some movie scenes that, while you're watching them, you realise that they are truly a sight to behold and must have been an epic struggle to film.

This week, the folks at WatchMojo have put together their list of the top 10 scenes that, in their opinion, presented some serious difficulties to directors and producers (and stunt teams) to pull off, and posed some serious problems in the process of taking them from the script to the big screen. 

The list includes Tom Cruise running up and down buildings in Mission Impossible: Ghost Protocol, as well as The Dark Knight and the beach landings scene from Saving Private Ryan, all of which have become pretty iconic since. All in all, we'd say it was worth the effort to get these done.
