Cocoon

“It is everything you've dreamed of. It is nothing you expect.”

The pool the old men keep sneaking into is full of alien cocoons. Arthur Selwyn (Don Ameche), Benjamin Luckett (Wilford Brimley) and Joseph Finley (Hume Cronyn) slip in from their retirement home, and each time they climb out they feel decades younger. Ron Howard keeps it gentle, and Arthur has to decide how much of his old life he wants back.
