Make Me An Offer Only Offer!

An offer I can't refuse...I don't know...
​So this was in my spam folder the other day (sorry, it got cut off; but you'll get the gist):

My first thought was..."is this a scam?"  
And then I thought: "Well, if it's a scam, it's pretty specific.  I mean, I could see if a Nigerian prince was interested in producing; but Amat Escalante is a real person.

My third thought was: "Well, if it is a legit query, why did it end up in my spam folder?  Is some imposter at work?"
I mean, I'm flattered that he finds "....great potential with your (my) masterpiece..." but I can't help but wonder, why would a Mexican director who works mostly in Mexico and in the Spanish language be interested in this very American book?
Or, could it be an absolutely genuine offer to buy the rights to 83 In the Shade?  Also what does "if you qualify" mean?
I guess the only thing to do is call the number, right?
Unless someone else out there wants to beat Mr. Escalante to the punch...Christine Vachon.
I'll keep you posted on future developments. ;)

Addendum: So I called the number on the email on July 22.  It's a U.K. number.  I got a message "your call can not go through because the called party is unavailable..." Hmmmm.  Curiouser and curiouser.  It was 7:30 pm there.  We shall see.
