The city of Los Angeles will be invaded by aliens on the silver screen with two upcoming films, Universal's Skyline, due in theaters November 12, and Sony's Battle: Los Angeles, which will be released on March 11, 2011, and both films could be at the center of a legal battle, according to Deadline New York.

A lawsuit hasn't been filed yet, but the site is reporting that Sony is considering taking legal action against Universal and Relativity Media due to the similar themes of both films. Skyline directors Greg Strause and Colin Strause are at the center of this potential legal battle, since Sony hired the brothers' visual effects company Hydraulix to work on Battle: Los Angeles and apparently the brothers never informed Sony that they were making their own alien-invasion film, Skyline.

Sony hired Greg and Colin in early 2009 to work on Battle: Los Angeles. The issue seems to be whether or not their access to Battle: Los Angeles materials such as the script and storyboard images formed the initial basis for Skyline. Sony claims that, at the very least, Greg and Colin should have informed the studio of their intentions to make Skyline.

While both Sony and Relativity Media declined comment for the story, a rep for the Strause's released a brief statement.

"Any claims of impropriety are completely baseless. This is a blatant attempt by Sony to force these independent filmmakers to move a release date that has long been set by Universal and Relativity and is outside the filmmakers' control."
