I watched the 2017 movie Beyond Skyline and it did not feel like a second part of a movie. Then on Wikipedia I read this line:
Beyond Skyline is a 2017 American science fiction action thriller film directed by Liam O'Donnell and stars Frank Grillo, Bojana Novakovic, Iko Uwais, Callan Mulvey, Yayan Ruhian, Betty Gabriel and Antonio Fargas. It is a direct sequel to the 2010 film Skyline.
How are the movies really connected?
