I recall seeing the E! THS about FH, and another actor was considered for the Danny part. Does anyone know who that actor is?

It was John Possey. I don't remember why he cancelled out on the rest of the series, just his name. I think it had to do with him wanting a different job or acting part, rather than play Danny on Full House or something like that.

I think they made the right decision with all the casting yes even including the olsen twins!

John Posey didnt 'cancel out'---THEY cancelled HIM because Bob Saget became available, and he (Bob) had been the choice for the role originally..

Oh yeah that's right. I forgot that part. Crazy me.
