GL Flash Team-Up TV Movie?

From Cosmic Book News

Three days ago saw a reported schedule released for the Warner Bros. DC Comics movies.
Among the list was a Flash and Green Lantern team-up said to be coming Christmas 2017.

Following the article, we were told that some of the list actually included TV movies.

Now it's been confirmed to us by a source close to WB that the Flash and Green Lantern team-up will be a TV movie on the CW.
We know that Grant Gustin recently debuted as Barry Allen in Season 2 of Arrow, and The Flash series premiers this Fall on the CW.
Green Lantern has already been hinted at in the Arrow universe with mention of Coast City and Ferris Air.
Last year saw Arrow EP Marc Guggenheim mention that using Green Lantern is something they have definitely talked about.

As both are set in the Arrow universe, we are guessing it's also possible the TV movie could feature Stephen Amell as well.
Amell is also set appear in the pilot episode of The Flash.

While certain parts of this make sense I still wonder about the movie side of it a Justice League movie should have Green lantern and the Flash in it, would this mean there are separate TV and movie universes or like Marvels Agents of Shield would there be a cross over between the two, guess we will find out soon.
