Question

В чем ошибка? The film is going to begin at 9.30.

Answer 1

Вместо going to begin надо поставить BEGINS

Answer 2

Ошибка в слове going и надо писать во так  nine the thirty

Answer 3

The sentence you provided is mostly correct, but there is a small error in the verb tense. The correct version would be:

"The film is going to begin at 9:30."

In this sentence, "is going to begin" is the correct present continuous tense to indicate a future event. It conveys the idea that the film will start at 9:30 in the future.
