Martin Scorsese and Robert De Niro to reunite?

Tis' a very good day my friends, a very good day indeed. The word on the street from the Berlin Film Festival, is that Robert De Niro and Martin Scorsese are planning to reunite for a 10th time, returning to the world of the mafia. A world in which they work so well.
Speaking at the premiere of his Lastest film, Shutter Island, in which he is working with Leonardo DiCaprio for the 4th time, Scorsese said:


"Bob De Niro (and I) are talking about something that has to do with that world, there's no doubt about that. We're working on something like that, but it's from the vantage point of older men looking back, none of this running around stuff." - Reuters. The last film the pair collaborated on was 1995's Casino.

For some reason, the rumour mill has been suggesting that the next time Scorsese and
De Niro team up, will be to ressurect one of their classic creations in Travis Bickle for a Taxi Driver sequel - though I can't seem to find any proof of this anywhere. After searching imdb pro, it seems like the most possible scenerio at the moment would be a film called I Heard You Paint Houses to be released in 2011. Again, according to the imdb, the story is as follows:

"[Based on the book by Steve Zaillian] A mob hit man recalls his possible involvement with the slaying of Jimmy Hoffa."



Considering what Scorsese has said, this sounds likely to be the most plausible option. I can't imagine why he would want to revisit some of his best work. Like the old saying goes "If it isn't broken, don't fix it". I can understand if Robert De Niro wanted to go back, however. But he should leave his greatest roles well alone. If it is to be I Heard You Paint Houses, i think sounds like a great project for everyone. Leonardo DiCaprio as a younger De Niro, anyone?

So, to conclude, i would like to get a poll going. What is your favourite Scorsese - De Niro collaboration and why?
