Zap2It is reporting that Jensen Ackles, who plays Dean Winchester in Supernatural, will be directing the fourth episode of the new series, which airs later this year.

‘Weekend at Bobby’s’, which marks Ackles' directorial debut, is the first episode to enter production in Vancouver. According to sources, the episode will centre on hunter Bobby Singer, portrayed by Jim Beaver, with a guest appearance by Kim Rhodes as Sheriff Jody Mills.

IGN is reporting that Smallville, another of the CW’s shows, will have a number of past guest stars returning to Superman’s hometown for its 10th and final season, including John Schneider, who played Clark Kent’s adoptive father Jonathan Kent.

It is unknown how Kent Sr. will return, seeing as he died at the end of season five, but the character will appear in the season premiere entitled ‘Lazarus’, and is expected to star in at least one other episode in the season.

Supernatural Season Six and Smallville Season 10 will begin on The CW on September 24, 2010. Both series will air in the UK sometime next year.
