Hi Francisco,

You're super close. I actually just finished this one. The only thing I think (I'm so braindead right now, but give it a shot) you need to change, is remove the "var" before leadActor in your if statement. It's already set as a variable before the optional, so you just need to assign the new value to it.

leadActor = movieActors[0]

Have fun,

Mike
