There are tons of apps like this just search on google market and find one you like best. A year ago or so I used one can't remember the name but on the tablet it could show a big poster of what was playing. Ideal for a sign outside your movie room to if you have so much space. (I don't) but I managed to cramp a 52" tv with full surround against one wall and a projector filling out one of the side walls out for those nights for special events. The second last wall has windows with a giant chair under it facing the projector wall, and the last one has my beloved sacufecus (sofa) so I can view both walls (tv and projector).
Ups kinda side tracked there but yes there are loads of XBMC android remotes including an official one I think.
