FOX previously held the Alpha Flight film rights. In 2003 they are referenced alongside Department H in X2 and were further eluded to in 2009's X-Men Origins: Wolverine; however, it is believed that the rights reverted in 2013 when they failed to further develop the property.

Evidence for this reversion belief can be found in Disney's trademark request on future film names from that year, which featured "Alpha Flight" alongside "Irredeemable Ant-Man", "Journey Into Mystery", "Strikeforce: Morituri", "Rocket Racoon", "New Warriors", "Guardians of the Galaxy", "Black Panther", and "Age of Ultron".(Source)
