Oldman would've been great as Renard, but for me Robert Carlyle could've been just as great. But since the character was so wasted - becoming a pointless side show after such a good build up in the first act (much like Hardy in Dark Knight Rises, who too was ultimately a woman's toothless puppet) i think Oldman would've done no better than Carlyle in that panto part.
Totally agree. The problem with "Renaaaaard" was not the casting, it was the writing. Carlyle can do scary (see: Trainspotting) but the script writers reduced his intensity to a handful of anarchist cliches (and some very hot rocks).
