In Return of the Jedi, Luke takes a blaster (using the forceForce) before falling into the Rancor pit. When he is next shown - now in the the Rancor pit - he no longer has the blaster. However, it doesn't appear that he drops it on the way down in the previous shot. So, what happened to the blaster? Is this a mistake that was made in production?
(The part that I am talking about is from around 24:46 to around 25:00 in the 2011 release of the special edition.)
