The Heat star will head an Arctic research team (his character obviously, not him) which comes faces to face with a deadly creature. But, before anyone says that sounds exactly like '80s Kurt Russell classic The Thing, the creature in The Thaw is prehistoric not an alien. So that settles that then.
Joining Kilmer will be Suberbad's Martha Maclsaac and Smallville star Aaron Ashmore. Mark Lewis is on writing and directing duties.
