Late 90s-2000s movie about mom moving her kids to hollywood

I was telling my friend about this movie but I can’t remember enough about it to be able to find what it’s called. Here’s what I vaguely remember
1. Dad dies and mother buys a gorgeous convertible with the insurance money and moves the kids to Hollywood to start a new life
2. At one point she removes the rear view mirror and says something like we don’t need it, we don’t care about what’s behind us
3. The ending was what surprised me – the older brother is acting in a movie and somehow the younger brother is scouted and he’s some kind of famous actor now.
