No, but the whole situation is at least as psychologically torturous for the eight-year-old girl as it is for the others, especially when the others start openly discussing killing her specifically. She screams and cries.
No actual physical restraints but they are all in a small circle that if they step out of they will die meaning they are forced to only stay in a tiny small spot.
*The other comment here should contain a spoiler warning, as it completely spoils the ending.* ----- We see no sets of parent and child. It's technically possible, though not very likely, that everyone who says they have children is lying - except, obviously, for the pregnant woman.
It emerges that two of the people present have been having an affair with each other. (Besides that, it seems that one other person present MAY have been having an affair with her married boss; she's accused of it and mocked for it pretty much out of the blue and doesn't deny it, but just cries in a way that may indicate that the accusation and remarks hit home.)
The shock that kills people every two minutes or for breaking rules is loud and jarring. The regular votes have a pulsing warning sound, but the shocks for breaking rules are sudden. There are also loud warning noises for infractions, and an alarm near the beginning to wake participants. The jumpscares are mostly auditory, (no monster faces jumping up in the screen) although the appearance of the beam of electricity may be startling as well.
I wouldn't say so. In fact, I found the lack of anxiety attacks extremely unrealistic, considering the situation the people are in. A few people cry, but nobody breaks down or "loses it". There's no hyperventilation, near-fainting, hysterical rambling or anything like it. Everybody acts suprisingly rationally or just stands there doing nothing.
No scene with an unusually tight space, although the characters are trapped in a large room the entire time and are killed if they step off their individual circles, so the whole film may feel claustrophobic.
A lesbian dies. She does not die first. There is a scene where a homophobic man asks her pointed questions until she outs herself and the homophobic man tries to convince everyone to vote for her, which would kill her. He claims this would end the trial. She fully expects him to succeed, but the group instead votes for the homophobic man, killing him. The lesbian dies near the end of the movie, in a tie vote where a number of other people die at the same time, so there is no point where the majority of the group voted for her.
I'm not sure why, at present, five people have answered yes, and nobody has answered no. Possible reasons: 1) A cop reaches for his gun, but finds that it isn't there. 2) Someone mentions that a relative of his was shot dead by a cop in the past. 3) People are shot dead with lasers coming from a faceless machine.
