Highlander 6 dream

Last night I had a dream that I was watching a show reviewing upcoming movies. One of the movies shown was Highlander 6.

From what I can remember the plot had Duncan trying to liberate a country (can't recall which one) from a tyrannical ruler. The Guardian was back too. In one scene Duncan had him on the ground, sword at his throat and he said something like "go ahead, you know what'll happen." I think Anna was back as well.

Also Duncan had his signature katana back. There was something about it being returned to him by an angel or someone from heaven as it was a part of him and he needed it.

One scene had Duncan fighting in a Roman style arena with a huge crowd of spectators. His opponent was a big green-skinned guy armed with a falchion and a skull-tipped mace that shot flames out of its eye sockets.

Anyone have any thoughts?
