the legality of using IMDB in an app

[cp123127]

I'm thinking of writing an app that will interface with imdb.com to search for movies and use IMDB's data concerning actors in a particular film along with each actor's filmogrophies. In essence, they are providing free movie data which I use in a non-free app. How legal would it be (how mad might IMDB get) if I were to charge for this app?
Should I use wikipedia instead although the data might not be 100% there or completely accurate?

I've seen lots of apps that deeplink into web sites, but for for-pay apps, you might be well advised by taking a good long look at IMDB's terms of use.

In other words, don't ask us -- ask them!

Ive seen many apps in the iPhone appstore that are pay apps and use IMDB data, and there has never been any problems - to my knowledge.

This is a app I really want now Ive seen sense and moved to Android.
