First and Last initial in your name with the same lead to success?  

well i got a triple as my intials and name and surname are SSS !! hahaha!

I seriously don't believe in all such superstitions. My first name and last name don't start with the same initials but I don't mind it at all. I'm a happy go lucky chap Hehehe...

Yep, I think it's 'catchy' so more people can remember it. I think the same is true for businesses, especially smaller businesses. Those that have two-word names that begin with the same letter are easier to remember.

When I was young, we had neighbors with a last name of Smedley. All of the kids, five in all, had first names that began with an 'S'. I thought it was neat at the time and still remember them all, all these years later.

Never heard of this. Never thought of it. Given your example, could be some type of "marketing" know how that indicates that this works. But I can think of many more successful people that don't have same initial names, so who knows.

I probally would say that though it may help, that the majority of the success would come from talent and hard work.

No I don't.
I never even though about that.
To me what stands out is whether or not the person can act. People like Tom Hanks. But I guess Sylvester Stallone needs all the help he can get.

i have heard people adding a latter or two to their names for inproved luck, but nothing like having the same initials repeated, may be there is a catch in that too

al pacino,

all these guys and many many others didn't and they are great successes, so I don't think that has any bearing on one's ability to do well in movies at all.
