Did you spot this mistake in the trailer of ‘Avengers: Endgame’?

Considering the mania around ‘Avengers: Endgame’, it is not surprising that fans have dissected every little thing about the film’s trailer, which released recently. In fact, various theories have been doing the rounds as to what viewers can expect in the film, which will release in April next year. So, when a diehard fan found a rather obvious error in the trailer, he immediately brought it to the notice of other fans.
If you jog your memory a bit, in the previous film, ‘Avengers: Infinity War’, in the climax scene where Tony Stark aka Iron Man and Thanos are fighting, the latter had broken the right half of Iron Man’s helmet. However, if you look closely, in the trailer as Stark is taping a heartfelt message in his helmet for his better half Pepper Potts, you can see that the left part of his helmet is broken.
Apart from discussing this rather obvious error, fans are also waiting for the next trailer, which will give them a clue about what to expect in the film. One theory that is doing the rounds is that time travel is expected to be a part of the script although the makers are yet to confirm the same.
