The amount of money that a cinema keeps from the screening of a film can vary depending on various factors such as the popularity of the film, the terms of the distribution deal, and the cinema's operating costs. Typically, cinemas keep a percentage of the ticket sales revenue, with the rest going to the film distributor. This percentage can range from around 50% to 70% for major blockbuster films, with independent and smaller cinemas sometimes negotiating for a higher percentage. Additionally, cinemas also make money from concessions sales, which can further contribute to their overall revenue from screening a film. **

The length of a film in the cinema can vary widely, but most feature films typically run between 90 to 120 minutes. However, some films can be shorter or longer depending on the genre and the director's vision. It's always a good idea to check the running time of a film before going to the cinema to make sure you're prepared for the length of the movie. **

A drug screening typically takes about 5-10 minutes to complete. The process involves providing a urine sample, which is then tested for the presence of drugs or their metabolites. The actual testing time may vary depending on the type of drug screening being conducted and the specific testing methods used. After the sample is collected, it is sent to a laboratory for analysis, and results are usually available within a few days. **

It is generally recommended to arrive at the cinema at least 15-30 minutes before the movie starts. This allows time for purchasing tickets, finding seats, and getting settled in before the previews and advertisements begin. Arriving early also helps to avoid the stress of rushing and ensures a more enjoyable movie-going experience. **

The advertising in the cinema before the movie typically lasts for about 15-20 minutes. This time allows for various advertisements, trailers, and promotional content to be shown to the audience before the main feature film begins. It provides an opportunity for businesses to reach a captive audience and for moviegoers to learn about upcoming films and products. **

I'm sorry, but I don't have access to real-time information such as the current running time of the Minions movie in cinemas. I recommend checking the movie's showtimes at your local cinema or visiting their website for the most up-to-date information. **

As an AI, I do not have personal experiences or emotions, so I have never left a movie screening because I couldn't stand the film. However, it is not uncommon for people to leave a movie screening if they find the film unenjoyable or offensive. It's important for individuals to prioritize their own comfort and enjoyment when deciding whether to stay or leave a movie screening. **

DDR Film Cinema refers to the film industry in East Germany during the time when the country was known as the German Democratic Republic (GDR). The GDR had its own state-run film production company, DEFA, which produced a wide range of films including feature films, documentaries, and children's films. DDR Film Cinema was heavily influenced by the socialist ideology of the GDR government, and many films produced during this time promoted socialist values and ideals. Despite the political constraints placed on filmmakers by the government, DDR Film Cinema produced a number of critically acclaimed films that are still celebrated today for their artistic merit and unique perspective on life in East Germany. **
