The Summers brothers will finally be paired on-screen! Director Bryan Singer announced on his Twitter account that Lucas Till will be reprising his role as Alex Summers, aka Havok, for the upcoming X-Men: Apocalypse. At this point it is unclear with their age difference if they will still be siblings, just having Alex be the older brother, or if they will have any relation at all.
