Factual error: Carol Danvers' name appears on her dog tags as "Carol Danvers," but US military dog tags list the surname first, then given name. E.g. "Danvers, Carol."
Factual error: New Asgard is in Tonsberg, Norway, but was filmed in Scotland. The truck Hulk and Rocket use to get there has a UK licence plate (SW61 5PN), whereas Norwegian plates use two letters followed by 4 or 5 numbers. Plus the pizza boxes in Thor's house have a phone number in UK format (01632 960776) not Norwegian. In fact, the 01632 area code is specifically designated for fictional use in the UK. Norwegian telephone numbers use fewer digits. (00:48:50)
Factual error: When the teacher announces they are going to Prague, they basically walk around the corner to a waiting bus. This is impossible because the part of Venice they are in is inaccessible to motor vehicles.
