After teaming up with his brother Shawn Wayans as an undercover cop duo in White Chicks, comedian Marlon Wayans is developing a new comedy series at ABC about two sibling police officers. Deadline says the potential new series is a hybrid single/multi-camera series will follow a down on his luck police officer who moves in with his brother and his family. Marlon will play the married brother, and while it's not clear who will play the other sibling, you would think Shawn would be an obvious choice, especially since he's also producing the series along with Keenan Ivory Wayans. The brothers have been working together along with their brother Damon since the days of In Living Color on Fox, and have teamed for the Scary Movie franchise and a couple terrible comedies. Maybe heading back to TV can get them back on their game.Details on Donal Logue joining Gateway, and Harry Potter cast member Tom Felton joining Labyrinth can be found after the jump.The forthcoming TNT drama series Gateway just recently landed a slew of cast members, and now another welcome face has just joined the cast as well. Deadline has word that Donal Logue, a man who deserves a successful series, but just can't manage to find one, has joined the cast. The series follows the Flynn brothers, Terence (David Denman), Daniel (Keir O’Donnell) and Jake (Cam Gigandet), as they step in to save their titular town in 1880's Colorado after their sheriff father is murdered, pitting them against a corrupt cattle baron determined to make the town his own. Logue is set to play Auggie, Jake’s drinking buddy, an aristocratic soul who inherited the town store from his father. This could be a great substitute for fans who were sad to see Terriers get the axe.Also, in the same source article, there's word that Harry Potter franchise star Tom Felton (who played the sniveling Draco Malfoy) has joined the cast of the four-hour miniseries adaptation of Kate Mosse's Labyrinth. Recently actors like Sebastian Stan and John Hurt were added to the cast of the project which tells the parallel stories of Alice, a present-day volunteer at an archeological excavation who discovers a ring with a labyrinth engraved on it and 13^th century new bride Alais, who is protecting books that reveal the secret of the holy grail. Felton is playing the character Raymond-Roger de Trencavel, Viscount of Carcassonne (that's a mouthful), who died in 1209 as a martyr trying to protect his Cathar citizens from genocide. Tony and Ridley Scott are producing the miniseries, but it doesn't yet have a distribution deal in the United States yet so stay tuned.
