In the below (very short) video Adam West and Burt Ward announced that there will be a new animated Batman movie that they will be providing the voices to. Burt suggest there is the possibility of a second film as well but for now they are focusing on getting the first one out in time to celebrate the 50th Anniversary of their original Batman show. The film(s) will run 90 minutes and so far that is all the information that is available with no word yet on who the dynamic duo will be up against or whether any of the other original cast members might make an appearance.

This happened on the 28th of March at Mad Monster Party but seems to have only caught on the last few hours and comes on the heals of the Batman '66 comic series which has also been collected as trade paper backs with Volume 2 coming out November last year.
