Thanks Trevor.I have worked out the rest except for type of success.
Thanks to R.Loblaw for your answer but it would make two of my other answers incorrect and i'm quite certain of those answers.It's really annoying as top billing sounds great.The other two clues and answers i have are as follows
1-main portion of the body-torso,which gives the o in the second word of the clue,(t-p,-o-r-n-)
2-well known for a bad reason-notorious,which gives the r in the second word(t-p,-o-r-n-),
any other possibles would be received greatly.Thank again for all your help.
