Deep Impact (1998) | Armageddon (1998)
Deep Impact
A comet is hurtling toward Earth and could mean the end of all human life. The U.S. government keeps the crisis under wraps, but crack reporter Jenny Lerner (Tea Leoni) uncovers the truth -- forcing U.S. President Beck (Morgan Freeman) to announce his plan. Grizzled astronaut Spurgeon "Fish" Tanner (Robert Duvall) and his team will land on the comet and lay explosives, hopefully deterring the object from its doomsday course. If not, humanity will have to prepare for the worst.
Armageddon
When an asteroid threatens to collide with Earth, NASA honcho Dan Truman (Billy Bob Thornton) determines the only way to stop it is to drill into its surface and detonate a nuclear bomb. This leads him to renowned driller Harry Stamper (Bruce Willis), who agrees to helm the dangerous space mission provided he can bring along his own hotshot crew. Among them is the cocksure A.J. (Ben Affleck), who Harry thinks isn't good enough for his daughter (Liv Tyler), until the mission proves otherwise.
