Lost in Space (Seasons 1–3)

Lost in Space (1965) is the classic sci-fi series you can watch online on iFILM. With Earth overcrowded, the Robinson family and pilot Don West set out to colonize a distant world aboard the Jupiter 2. They never make it — the ship is flung off course on its very first voyage.

The culprit is Dr. Zachary Smith, a saboteur who sneaks aboard to wreck the mission and ends up stranded with the crew for years. He spends his days tormenting the family's Robot, who in turn becomes the closest friend of young Will Robinson. Each episode strands the castaways somewhere new, from hostile alien worlds to space pirates and traps left by long-dead civilizations.

Created by Irwin Allen, the show ran three seasons on CBS and gave pop culture the immortal warning "Danger, Will Robinson!" It begins as a straight survival story and slides into pure camp, with the bickering Smith-and-Robot double act carrying half the run. Stream Lost in Space (1965) online on iFILM.
