This question is good for 24 hours or until Feb.23, 12.00 pm and if
the answer is not Treat Williams, because Irulrick have given a
comment about this.

"On film, he battled dinosaurs, romanced Ann-Margret and advised
Harvey Keitel. Name the actor. "

treat williams-
 Street Car Named Desire with A M
Mens Club with H K
 no dinosaurs with him but I found a monster (deep rising) and a gaint snake movie

Thank you for your comment, I'll keep this answer for a last minute
answer, and if this is correct you can claim the price. I'll let you
know on Feb.28 maybe.

Dennis Quiad---- starred in "interstate 60" with HK
"any given Sunday" with AM
and dino movie by the name of 'Caveman' - Semi-amusing comedy set in
prehistoric days...Quaid was just getting started, you know!

but there's no romance between DQ and AM in this movie.

"Pat Boone", maybe (?)
  
There was romance with Ann-Margret in "State Fair", and, "Journey to
the Center of the Earth" involved dinosaurs. I don't know where Harvey
Keitel fits in though.
  
"State Fair" - http://us.imdb.com/title/tt0056526/
   
"Journey to the Center of the Earth" - http://us.imdb.com/title/tt0052948/

Treat Williams starred in "Journey to the Center of the Earth" 1999 with dinosaurs!

Thanks for your comment, the problem in here is that this is a Movie
TV, the same as a streetcar named desire, that's why I give a note
that answer with Treat Williams is  belong to Irulrick after I know
the real answer.

Please claim your answer for Treat Williams, so I can close this today.

As I am not a google researcher, due to some unknown reason for them
not hiring me as of yet... I can not claim the answer. I am taking it
that I may have been correct? True thanks would be telling google to
hire me already. But I am content on "commenting" just for the fun of
it, so it doesn't really matter much either way! :D :D :D
