Hi all from Italy and sorry for my english!

I'd like to know why, in your opinion, there is no bonus material in Jeffersons dvds... I've bought Three's company and I've found several extras... It's strange there isn't -for ex- an interwiew to Sherman Hemsley or Marla Gibbs... When the first dvd box set was published I remember Isabel Sanford was still live... I thought to find some behind the scene, bloopers... but nothing! Someone has an explanation?

Thank you,

Giuseppe
