Corrected entry: After several minutes of the boys evading the federal agents on ther bikes, ET uses his telekenetic powers to make the boys and bicycles fly into the air (when they are confronted with the roadblock, with agents with either guns or walkie-talkies, depending on the version). If he really had those powers, however, one would think he would have used that earlier, rather than having the boys jump dirt mountains and evade cars.
Corrected entry: Phases of the moon - when Elliot first goes to the backyard to find ET, the moon phase is either the first or last 1/8. The next night, there is no moon (okay, so maybe it was a different time of evening). But then the next day, when the kids are taking ET to the mountain, the moon is full. The moon never goes from 1/8 lit to full in 2 or 3 days.
Corrected entry: At the beginning, when the men are searching for E.T., the keys on the "Key Man" keep changing sides between shots.
Corrected entry: Mike and Elliot hijack the van holding E.T. and abandon it in a park, which is shown to be a significant distance from their home. When the Feds and Elliot's mother (Mary) finally show up at the now abandoned van, Harvey, the family dog, is shown waiting for them at the rear of the van. How did Harvey get there? He didn't go in the van with Mike and Elliot. If you look carefully at Mary's car when she is backing out of the driveway, you see that there is no dog, only Mary and Gert. Even if Mary did take the dog, it is shown being there before they arrive at the park.
Corrected entry: When Elliot and his brother are driving to the park to rescue E.T. there are two men riding along in a plastic tube connected to the van. There are two black ropes inside of this tube in which the men are trying to use to approach Elliot. When Elliot unhooks the tube from the van the ropes continue to hang from the back, and drag along the street. In the next scene the ropes have disappeared.
Corrected entry: When Elliot and his brother are searching in the garage for items to help ET create his "phone", the garage door is obviously closed, and they are using flashlights to see what they are looking around for. However, right outside, the government agents are spying on an open garage that has all the lights on. They go back and forth to the kids (dark garage) and agents (open, lit up garage) a few times.
Corrected entry: The federal agents find ET's communicating device in the woods (as evidenced by the lead investigator's question of Elliot as to the purpose of the device). In a later scene, Elliot returns to the woods and the device is still there. It has not been taken by the federal agents, and it is not being monitored. It is of course inconceivable that the federal agents would not take the device or monitor and protect it.
Corrected entry: When E.T. and Elliot are flying through the air on his bike, E.T. is wrapped up in his Halloween costume. From the time they get on the bike to the time they land, E.T.'s facial view goes from being completely covered to partially covered (wrapped all around his head and chin) to having the cover just hanging off the top of his head. It would have been impossible for E.T. (his arms wrapped in the costume) or Elliott (managing the bike/handlebars) to rearrange his sheet.
Corrected entry: Elliot first encounters E.T. in the shed behind his house and in the cornfield by his house. Why is it that the next day, Elliot went to the exact place where E.T.'s spaceship had landed the night prior in the woods and laid down Reeces pieces? How could he have known that's where E.T. had landed when he saw E.T. by his house? (00:12:50)
Corrected entry: When the boys take off in the air on their bikes it is day time, but when they land, it's night time. It cannot be that far from Elliot's house and neighborhood to the woods because they walked or rode bikes there on Halloween night. There therefore is not enough time to go from day time to night time in the time it takes them to get to the wooded area. Also, Elliot's mother started her drive to the site in her car when it was still light, and she arrived when it was dark.
Corrected entry: During the dinner scene at the beginning of the film, Drew has half a hamburger on her fork. The next time you see her the hamburger is full.
Corrected entry: If E.T. can fly, why doesn't he just fly to the ship in the beginning instead of running and missing the takeoff?
Corrected entry: When E.T. is dressed up for Halloween and walking with Elliot and Michael, we see his view of the other neighborhood children through his ghost costume. The eyeholes on the costume are at least 4 inches apart and yet E.T.'s view (thru the camera) shows only a sliver of material between the eyes.
Corrected entry: E.T. is noticeably alot larger than Elliot's bicycle basket. How in the world did he fit?
