Though only October, 2015 will soon be upon us, and with it the return of Showtime Sunday favorites like 'House of Lies' and 'Shameless.' And where the latter skewed a bit darker in season 4 (despite moving to the comedy section for Emmy purposes), the first full trailer for 'Shameless' season 5 sees Fiona and the Gallaghers returning to their destructive ways, with a few new (and returning) faces plenty visible.

Despite a season that saw Fiona (Emmy Rossum) taking a brief stint in jail, the Gallaghers looks to be in all kinds of trouble when season 5 picks up in January, particularly fighting the neighborhood's gentrification. And where season 4 ended on the shocking return of Justin Chatwin's Jimmy Steve Jack, the character is only alluded to by the trailer, as Fiona races into traffic to chase down the familiar-looking man.

In addition to Dermot Mulroney's role as Fiona's new boss, 'Shameless' season 5 will also feature 'Rizzoli & Isles star Sasha Alexander as one of Lip's college professors, along with 'Home and Away' star Axle Whitehead, and 'Rake' alum Bojana Novakovic. You can check out the first season 5 trailer for yourself above, and tell us in the comments what you want to see when 'Shameless' returns for another round of Gallagher debauchery in early 2015!
