I've setup a wedding party for two of my sims and it was the meaning that her dad would film the wedding.
One thing I've noticed about this: a five star celebrity gets mostly interupted with questions about signing autographs before he got 10 seconds of shots. Therefore, he was more busy with his own reputation than with his daughter's wedding day.
'Dad, you've promised to give me away today!' 'Not now honey, I've just been asked for another autograph. You're wedding can wait, it's not THAT special.'
Conclusion: celebrities and recording home videos don't go hand in hand.
Be warned!
