Your safety demonstration video actress is very sultry. In fact, she made me seriously consider my heterosexuality. I found her especially enticing when she made that "you are being naughty" gesture when advising passengers that smoking is not allowed.
However, I feel compelled to point out to you that while she did capture everyone's attention, is 'stimulated' really how you want your passengers to feel prior to take off?
Additionally, while her attractiveness cannot be denied, it my serve you to realize that your passengers are not all rich middle-aged men who can afford such eye candy and bi-curious, sexually confident women. Thus, I'm concerned this video is not supporting a respectful passenger/flight attendant relationship, given that post video many will be fantasizing about joining the mile high club, rather than following crew instructions.
Finally, in the interest of equanimity, if you are going to keep that particular video, than it's fair for those who are female heterosexuals or male homosexuals to see an equally attractive male actor. I prefer Daniel Craig or someone of equal caliber.
