I guess someone somewhere must be asking for this kind of thing, but my impression was those type of interactive features were never terribly popular when they were on Blu-ray and were more of an annoyance than anything else: Who wants to sit through the whole movie, just waiting for bonus...
WB is also releasing restored versions of The Max Fleischer shorts on Blu-ray in May. Since the press release makes no mention of restored versions of the shorts, it's probably safe to assume that what's going to be included on the BDs in this 4K set will be the same 480p versions as before. :huh:
