LL Cool J -- Too Soon to Think About a Christopher Dorner Movie

LL Cool J must know he bears a striking resemblance to accused killer Christopher Dorner, but he wants NO PART of a movie about Dorner ... at least not yet.

Outside Katsuya in Hollywood last night, we asked the Grammy host/rapper/"NCIS: Los Angeles" star about possibly doing a biopic, but he quickly nixed the idea.

LL told us, "That's not even something to really talk about because there are families that suffered, people that died. And because of that, I think it would be disrespectful to them to ... have this conversation about a film when people's lives were on the line."

Always classy.
