Artists who I think dont kill tamizh every time they open their mouths are/were..
Sivaji - his diction was awesome
SSR
Major sunderrajan
kamal
Padmini
Manorama
Vijaykumari and most old actors and actresses barring a few.
People who should try to speak this language
better are
RKanth
VKanth - useless case
Karthik - atleast the SS has the excuse of not being from this state...dunno whats the matter with this one.
Vijay - never understood why he ate the words??!!!
Ajit - :huh:(maybbe coz mom is sindhi and dad is mallu or something like that??)
Almost all the other new actors and actress.Infact I cant think of the last actress who dubbed in her own voice and did a good job !!
Ive never heard simran speak in tamizh so cant say anything about her tamizh but kushboo and devayani deserve a special mention coz they atleast learnt the language and tried to speak it correctly!
Amongst the newest actress asin also derservs a mention coz she did dub for her last 2 tamizh films and did an ok job of it.
