IMBb has released a big update today to its iPhone and iPad app, adding the the ability to purchase movie tickets directly from within the app and much more. The feature is initially only available to users in the U.S. and can be accessed directly through a “Showtimes & Tickets” section on listings for movies currently in theatres.

IMBd has added even more celebrity bio pages in today’s update and iPhone users now have “one-tap access to the full cast/full filmography.” The updated app also includes a few other UI enhancements and bug fixes listed below:

What’s New in Version 3.3

iPhone

  • We heard you. By popular demand, we’ve updated the movie and celebrity pages to include one-tap access to the full cast/full filmography (which, yes, scrolls vertically).
  • You’ll see that cute little Watchlist flag almost everywhere now. Tap it to add movies and shows to your Watchlist (and tap-and-hold to add to your other lists as well).

This will be the last update that supports iOS 5. Future updates will require iOS 6 and above.
