The first “Men in Black” is one of my favorite films of the 1990’s. The second was a terrible disappointment and clearly hacked up before release as shown by its slim running time and unsatisfying and conclusion. I keep hoping there is some director’s cut coming some day. I’ve been worried about the third in the series because of reports of chaotic filming and rumors that there was no script and they were making it up as they went. This new trailer looks encouraging, so here’s hoping.
