This kind of attitude makes me want not to help. Are you aware that you are
saying this to the one of persons responsible for the huge improvement of
ffmpeg's documentation in the last few years?

The documentation for the 0.10.6 release comes with the 0.10.6 release, in
the doc/ directory. The documentation for the movie and overlay filters have
been constantly kept up to date since way before the 0.10 branch.

This exact same command line, just changing the inputs and output to file
that I have, with a fresh build of 0.10.6, works perfectly.

You should be seeing an info line related to movie and two other related to
overlay, around here.
