K, when you write this, make sure you stick to the Plot Point formula.
Meaning: Make sure something happens from Act 1 to Act 2 that flips the story around in a different direction. Same from Act 2 to 3. Try putting a mini one in the middle of Act 2. Act 2 is supposed to be double the length of the other acts, but this formula does not need to be followed. But it reads and sells good.
So, make sure the Flashbacks to interfere with that, unless the Flashback reveals something that flips the story around, which is actually a very good Idea. It would be very different, new and fresh.
If your flashbacks isn't a main ingredient in your story, then it'd be good to cut a lot of it out. But if it's needed for Plot purposes, just use the ones that really aid the plot.
You could do the, Flashback Present process. But if the story isn't meant to be like that, then it what fuck everything up and throw the reader off.
The bad thing about Flashbacks is; In your script, tension is built up like a roller coaster, reaching the top, ready to fall. But when you throw flashbacks in, it effects that build up. And drags everything on. So, thats what I mean by dont let it effect your plot points or Climax. I had a very very well written flashback scene in the third act of my script. It showed how the lovers met before all the crazy shit went down. My idea was to make you feel more for the characters, and know how things happened, but thats what act 1 and act 2 are for. By act three, the characters are introduced and the Climax is building. That scene I added would have ruined the climax. So don't let it ruin the climax. And a good idea is to keep it short.
Something I like and I think would work very well, is to do Act one without any of the flashbacks you wrote. And after your characters main problem arises and the story is flipped on its back... Example, In Alien, the first ten pages shows who the characters are and what their purpose is. Then, about 20-30 minutes in (Each page equals one minute of screentime) the Alien egg hatches on to the guy, and then the things bursts out his chest later. The story is flipped around now. Now, an Alien is running around their ship. At the End of Act 2, you find out who the traitor is and the purpose of the mission. Flipping the story around.
So, with this in mind, Try going through Act 1, showing the characters and the major conflict and after the first major thing happens. Do an entire Flashback scene of all the flashbacks. This way, any thing that they refer to in the first Act, that refers to a memory, the flashback scene will make it all make sense. Its a stylish way of going about it to. Then once the flashbacks that are refered to in Act one are done, continue with present time and go through Act 2, having them refer to more memories. Then, once another plot twist or turn happens, do another flashback scene filling in the pieces. This is something I have never seen before and It will work as long as it is fast, and the memories are exciting. Don't make them dreadful, for when it happens the second time, they dont say " fuck, not this again." Lol
What you think about that?
