The Sims 3 Late Night Film career is divided into 2 branches: Directing and Acting.
It’s a sort of hybrid career, as you also have to do few extra jobs that the player can control.
It’s perfect for celebrities and for the ones that wanna party the whole night, because you don’t have to work in the morning and in the worse case you start at 1 pm.
The job place is the movie set, that can also be visited by normal Sims for a tour or to watch a movie.

The Sims 3 Late Night expansion pack introduces 2 new traits: Star quality and Shy.
Below you can see their details…

STAR QUALITY
Sims with this trait become celebrities with not too many efforts and can impress other Sims (both celebrities and normal) easily. Their celebrity bar increase faster and they receive discounts and free items quite frequently.
Suggested careers: Movie, Journalism, Business, Professional Sport, Politics.

SHY
Shy Sims doesn’t make friends easily. They don’t feel comfortable when there are no friends around and get a negative moodlet for that.

In The Sims 3 Ambitions, children can earn few simoleons by selling baked goods... are you ready to become a little businessman?

What you need
To start this business you need a starting budget of 125 Simoleons. Go to Buy Mode, click on “Sort by function” and enter “Children” category. Now, buy “The baker's half dozen stand” (§75) and “Rip. Co. Little Baker Oven”(§100) and place them in the lot. It would be better if they stay outside, as your neighbors will be the customers.

What Lifetime wishes are?
Lifetime wishes are the goal of your Sims’ life. You can choose it when you create a character in CAS or when you become a young adult in game. Once fulfilled, they give you around 30.000 lifetime happiness points, that you can use to buy Lifetime Rewards.
They sometimes appear between children and teenagers wishes (you can recognize them because they are gold). If you choose your lifetime wish in this way, you won’t be asked to select it again when you become a young adult.
In live mode, you can read your Lifetime wish details at any time. There’s also a counter that let you know how many requirements you still need to fulfill it.
