This is something that I see frequently, including in a screenplay for which I'm currently providing feedback. It goes something like this.
Ext. Alley - Night
Joe sprints down the alley with Stan right behind him. He turns the corner, spies an open door, slips inside. Stan runs right by the door.
Int. Bar - Night
JUDY
How did you lose him?
JOE
I was damn lucky! There was a door open and I stepped inside. He wasn't more than a foot away when he ran by.
------
This type of scene usually goes on much longer than this, but that's the general idea.
We just SAW (ok, read) what happened. This will flow better and keep your script tight if you join the scene between Joe and Judy AFTER he tells her what we already know. Pick it up with what he found when he stepped inside the door, or the fact that it smelled like bbq, or who was in the store where he found himself, etc.
