Still less in the great actor's iconic role as boxer Jake LaMotta in Raging Bull.
That did not deter David Cameron yesterday, however.
The Prime Minister used his weekly row with the opposition in the House of Commons to allow his imagination to run wild.
His focus was this week's battle between Labour and the unions.
The Labour leader had gone to the seaside to address trade unionists and "bottled it", the Prime Minister said.
"He had folded faster than a Bournemouth deck chair," he shouted, to what appeared to be a distant cry of "boom, boom".
Finally, he added with a flourish, Mr Miliband had promised us "Raging Bull and he gave us Chicken Run!".
You can see the point that Mr Cameron was making.
Well, you can if you forget the numerous boxing matches in the film which LaMotta loses.
Still, we just about got the point.
One is an Oscar-winning Hollywood heavyweight.
The other is, well, Chicken Run: regarded by some as the Aardman's least best film.
Plus, as the more astute political observers will have quickly noted, it has the word "chicken" in the title.
The Labour front bench did their best to appear as if they did not care.
Mr Miliband and his shadow chancellor Ed Balls looked over their shoulders at the benches behind them at one point, as if to say "who, us?".
They need not have worried.
Parents of small children and film fans everywhere could have told them the difference between Chicken Run and Raging Bull.
Chicken Run has a happy ending.
