"Six Feet Under"Gets Gayer!! Those stories that you've heard about Mena Suvari playing a lesbian on the upcoming fourth season of "Six Feet Under" are true. Gaywatch has screened the first four episodes of the new season, which starts on HBO Sunday, June 13, at 9 p.m. EST, and was delighted to see the charismatic Suvari in the role of Edie, a wild lesbian poet who reawakens the artist in Claire (Lauren Ambrose). And don't be surprised to see the bold Edie awaken more than Claire's inner artist: Judging from Claire's obvious fascination with Edie, it seems inevitable. Suvari's Edie makes her "Six Feet Under" debut in the second episode (Sunday, June 20) of the season. Aside from Suvari, other guest stars this season include Ellen DeGeneres, who makes a cameo on the third episode (Sunday, June 27), and former "Buffy the Vampire Slayer" star Michelle Trachtenberg, who debuts in the role of a spoiled pop diva named Celeste on the third episode. Returning guest stars include Kathy Bates, who is so wonderful in the role of Bettina; Patricia Clarkson as Sarah; Joanna Cassidy as Margaret; and Rainn Wilson as Arthur. A season premiere preview: Nate (Peter Krause) wants to do right by his late wife Lisa (Lili Taylor) and fights with her parents over what to do with her remains; Federico (Freddy Rodriguez) gets entangled in the life of stripper Infinity, a.k.a. Sophia (Idalis DeLeon); David (Michael C. Hall) and Keith (Mathew St. Patrick) mend fences and agree to start over; Brenda (Rachel Griffiths) gets intimate with her neighbor Joe (Justin Theroux); Claire makes a confession to Russell (Ben Foster); and Ruth (Frances Conroy) and George (James Cromwell) enjoy married life -- the sex in particular -- to the disgust of the others living in the Fisher house. Nate and Federico's stories are the most emotionally engrossing in the opener and remain so over the course of the next few episodes. You feel for Nate as he struggles to cope with Lisa's death and move on with his life, and you want to save Federico as he foolishly falls deeper into a situation that could destroy his marriage. Still, you can't help but be intrigued by the possibilities of Claire's blossoming friendship with Edie. And then there is a mystery of sorts to figure out: Let's just say that George receives some packages from an anonymous sender containing unwanted "gifts." One criticism: David and Keith's relationship is getting tired. After reuniting, the pair is at odds yet again when Keith lands a position working security for celebrities and chooses to hide his sexual orientation on the job, joining the other security guys in ogling women. Does anyone who knows Keith's history believe that he would duck back into the closet? The development is oddly out of character. Incidentally, if you happen to miss some or all of the first three episodes of "Six Feet Under" this season, HBO will air all three back to back on Sunday, July 4, beginning at 8 p.m. EST.
