Continuity mistake: When Mary gets her first look at an ailing E.T. lying on the bathroom floor, she panics then hurries everyone downstairs - leaving E.T. behind. Moments later one of the astronauts happens upon E.T. and now a bright pink bath towel can be seen draped over the bathtub's edge, which wasn't even there to begin with. (01:16:00 - 01:17:55)
Continuity mistake: When Elliot burps, the pencil on his desk disappears between shots. Also, the paper swaps from laying on the edge to several centimeters away.
Continuity mistake: When Elliot shows up the morning after Halloween her mum hugs him and gets dark paint on her cheek. When the angle changes the stain vanishes.
Suggested correction: Mary doesn't get "dark paint" on her cheek when she hugs Elliot. When Mary's standing at the fridge door speaking to the police officer, she's still wearing her Halloween dress and the mark on her right cheek is the black heart (part of her Halloween makeup), which is still on her cheek when she sits Elliott down on the kitchen seat.
Right after she hugs Elliot there's a wide angle where she says "Sorry" and her cheek is spotless. Screenshot can be submitted if necessary.
Revealing mistake: When ET is grabbing things from the fridge, in the close-up his fingers swap from thin and long to chubby and short, obviously a puppeteer's glove.
Continuity mistake: When ET's spaceship takes off and starts flying, the sky is red, a shot later it's blue.
