Stupidity: Gargantos neutralizes Strange's cape tossing a motorbike at it. Hilariously enough, someone was riding the motorbike and Gargantos knocked him off the bike. The streets were littered with all sorts of wreckage; the biker who made a conscious effort to drive around all sorts of obstacles literally blocking 90% of the roads and ride right at the enormous monster in plain sight must have been in a hell of a rush.

Stupidity: During the battle with Shuma-Gorath / Gargantos, Strange summons a variety of items that cut or would cut through him like butter (a single shard of the bus, a magic weapon, not to mention a massive circular saw), but he just doesn't use them anymore for no reason despite them being super effective. At one point Wong and him even try to pull the kaiju-sized monster to the ground using their physical strength, failing as anyone (but them, somehow) would expect when the monster was paying them no attention for a long time.

Continuity mistake: When America says "Find food. Preferably pizza", the passers-by change in the mid-sentence cut.

Continuity mistake: At the wedding, Christine tells Stephen something quite hurtful; wide-eyed, he asks her how long did she have it in the barrel; a black partygoer walks behind him but is gone in the reverse shot. Moreover, she replies "Long time" and a couple walks past her, only to walk again past Stephen in the next shot.

Continuity mistake: When Christine and the groom have a look at the battle on the nearby building, in the shot from the front you can see to the left a very excited guy hop from foot to foot with his mouth open. In the angle with the camera behind Christine, the guy is directly next to her, but there were a couple more people between him and the bride.

Stupidity: Wanda's kids when she is possessed by the Scarlet Witch notice that she is walking two feet away from the sink and assume that she's going somewhere, but they didn't react at all to her breaking dishes, staggering, the lights flickering and the lamp moving wildly, etc.

Continuity mistake: When the hero of the movie savagely tortures for weeks a guy who dared to touch his mantle after being robbed, the mustard on Bruce Campbell's clothes changes position from shot to shot.

Continuity mistake: When we first see Wanda with her kids (which turns out to be a dream, but it's also showing a glimpse from another universe, and it's not meant to be 'out of order or unnatural) she tries to tuck one in, and he refuses. Wanda pulls back, but in the next shot she yet has to.

Continuity mistake: When Strange reveals the presence of the tentacular monster, a person is running across the street behind him with their kid, but they're gone (or rather, several meters behind the original position) in the very next shot.

Continuity mistake: At the wedding, Christine tells Stephen that he "deserves it"; she leaves pulling her hand off his tie, but she never put it there in the first place.

Sammo ★

Continuity mistake: Stephen performs a magic trick very popular at weddings a couple millennia ago changing water into wine; as he does that, you can notice that the barman in close-up is bent over behind the counter, but he was standing a moment before when Strange started the gesture.

Other mistake: In the theatrical end credits, Alan Silvestri's credit under the Captain America theme was misspelled as SilveRstri. This was fixed for home streaming.
