I'm a film fanatic (I am @film_girl, after all) and as an Atlantan, Turner Classic Movie has always held a special place in my heart (except for that period of colorization, which we should just try to ignore). TCM airs more than 300 movies every month, all uncut and commercial-free, spanning different decades and periods of film history.
What you might not know if you haven't been to the TCM website before is that it also has quite a wealth of information and historical data, as well as essays about films and different genres. The iPhone app brings much of the best aspects of the website to your phone.
The schedule lets you see three months worth of data, and you can select a seven-day view or choose a specific day on the calendar. On February 1, TCM starts its annual "31 days of Oscar" celebration, and I only wish there was a search feature, similar to what HBO has for its app, to make it possible to find and set reminders for showtimes. When you click on a film, you can read a full synopsis, cast information, trivia and see any essays or other stuff related to the film.
There's also a collection of film clips and trailers (small now, but hopefully growing) that are presented in the correct aspect ratio. It's really neat to see how movie trailers from the 1950s and 1960s looked. You can also view photos and press kits from select films, look at classic actor and actress images, and see stuff like posters and lobby cards. You can also read the latest entries from TCM's movie blog, though I wish the entries were a little better formatted for the app. Images are not clickable and text isn't spaced out in a way that makes it easy to read on a handheld.
Qualms aside, this is a good app with lots to enjoy for TCM and classic movie fans.
While just on the iPhone for now, TCM plans to release a version for the Android and BlackBerry platforms in February.
