When you finish the King Kong scene, director Willis tells you to meet him at Post production, which is in a building a block to the left. Finish that, and you get the film to take to the theater.
When you finish Sound Stage 4 (King Kong scene), you are prompted to go to the Post Production building, a block to the left, to edit the film and sound.
Complete the tasks on all 4 sound stages, then edit the film in Post production (just left of sound stage 4). Take it to the theater and climb up to show the movie.
The script writer, Goldie, is on the roof of Sound Stage 1.
Just climb up from either side.
It is just left of Sound Stage 4, which is down in the lower right corner of the studio lot. From Sound Stage 1, Sound Stage 2 is 2 blocks to the right. From Sound Stage 1, Sound Stage 3 is three blocks down. From Sound Stage 1, Sound Stage 4 is 4 blocks down and 3 blocks right. From Sound Stage 1, Post Production is 4 blocks down and 2 blocks right.
When you are at a sound stage (1, 2, 3, 4) or later at the Post Production building, get your cart close to the sound stage and click "enter" where it appears. You cannot get out anywhere else.
Once you are in the studio, just walk left from Sound Stage 1 and the gate to the street will be open to come and go.
When you are anywhere inside the studio, drive back to Sound Stage 1 and walk left to exit onto Sunrise Street. The gate is now open.
To leave the studio, you have to drive back to Sound Stage 1. Then you can walk left to exit through the gate. Once you are in the studio, you can come and go as you like.
The only time you ned to reach ledges are on the theater (the red eves are like flippers) and on the Sound Stage (climb up equipment).
You are on Main Street (Sunrise Street) when you start. To leave the studio and go back to the street, drive to Sound Stage 1 and just walk to the left -- the gate is opened from the inside.
Walk left from Sound Stage 1 and push open the gate. Evidently there was another lock on the inside to release the chain.
