I hadn't seen the trailer in theaters so I made the mistake of watching the trailer on the Ali DVD. It has what I think is a MAJOR spoiler! Don't worry, I won't reveal it here. I didn't know how they were getting Tommy Lee Jones back after he had his memory erased in the first MIB, until I watched this trailer. It's no secret they are, but I purposely avoided finding out the method and how it plays. This stupid trailer reveals everything about it, and gives away some great jokes too. It explains way too much! Now I know how they get K back and why! ARRGHH!!! Why do the studios do things like this?! It just ruined a major plot point in a movie I was looking forward to seeing. Now I don't know if I'll go, out of sheer principle! You suck, Columbia/Tristar!!! Blunt, yes, but I mean it!
