Yes, it increases your chances but it is not necessary.
So, why do CFA or FRM? These are courses for individuals interested in specific fields. CFA (Chartered Financial Analyst) is for the ones who want to go in money/asset management. Those interested in equity research and analysis finds this course interesting. FRM (Financial Risk Management) is for those interested in risk management of various investments. So pursue these courses only if you want to go into that particular field and are genuinely interested. CFA takes almost one year for each level. There are three such levels. Only having level one will not help much for your career. During the interviews for admission it will surely sow your interest in finance as such. For CFA you need to put in lots of hours of study, so if you are not interested don't do it. Most of the students entering IIMs don't have a CFA. So it is okay not to have such certifications. Just go through the portions of the exam and see if you are interested.

ACCA has the same career prospects as a CA in India. You can practice accounting in any company you wish. You can join consulting companies like Deloitte and PwC, or any other company. A starting salary of 4 LPA is what you can expect initially. The best thing about ACCA is you can get a good number of opportunities abroad whereas CA doesn't have as many opportunities abroad.
Again the problem with ACCA is, in India companies prefer a CA because they are well acquainted with accounting practices followed in India and are familiar with local laws. But, that doesn't mean that ACCA has no opportunity. Start your career, work hard, you will become successful. In field of accounting the people with skill and knowledge are valued more. Be good in your field, it would not matter if ACCA or CA.

Screenwriting is a process of writing a script, but this is only used for filmmaking that has narrative elements that involve dramatic elements and other components of the film that need to be seen on the screen to serve the overall narrative like the setting, the lighting and movements. Screenwriting provides the visuals that complement what the characters are doing and saying. The mood accentuates the drama or humour that the characters are executing based on the script.
It deals more with how the story is going to be perceived by describing where the characters are, what they are doing, what they are saying and everything else that's happening around them. It may not even include character dialogues to accomplish this.
