and yeah, the only guy in highlander i had a crush on was methos, and the only guy on supernatural i have a crush on is castiel, so there is that.
but lo and behold, here i found out a movie that will probably be very poorly received, Stonehenge Apocolypse, will have both castiel's misha collins and methos's peter wingfield.
ps. they were also both on 24, but at totally different times.
eta: stonehenge apocolypse is a syfy original! so it is guaranteed to be bad, but it also might be 'good'.
