Facundo Arana is doing all of his stunts. In March 2006 he broke 2 thumbs during the filming of a race.
Natalia Oreiro trained daily for three months prior the starting of the filming with boxer Marcela "La Tigresa" Acuña and her husband/trainer. Since the filming has started she is still training three times a week.
On the day of his 34th birthday Facundo Arana received a pilot license. For the episode 78 he flew a small airplane with Natalia Oreiro on board. She said in an interview that she promised him to do so when he receives his license though she did not think it would take so little time.
