Yes, they are wonderfully monomaniacal at that age. With our son it was initially Dumbo which was probably viewed about 270 times over the course o 6-8 weeks, then it was Lady and the Tramp, and I can't remember what came next. At least he did not involve us in whatever cartoon world he was living in. That came later when those absurd Ninja Turtles required the liquidation of a trust fund to finance the acquisition of them and all the accessory paraphernalia that their world entailed.
