you can watch it HERE if you missed it. But the Lone Ranger trailer 3 was also released and it looks better than ever!
Strangely, the french version of the trailer 3 also posted today on Youtube is very different with many shots that don't appear in the american one. I post it below, but this one is dubbed in french - Walt Disney Studios France also released the same one in english with french subtitles but for an unknown reason only the first 20 seconds can be watched. You might try HERE anyway, may be it'll work in its entirety for you.
