Who would you cast, or who do you picture, as the characters of the Marauder Era?

When people write Fan fiction, make fan art or fan vids, you often see the different interpretations of different creators and you often see them use different actors to the ones that you would use or picture as the characters.
So I have complied a 'Gallery' of sorts to show who I picture when I think of the characters from the Marauder Era.

Just to clarify, in the picture I've included, the 'cast' is as follows:
Top Row: Andrew Garfield (James Potter), Karen Gillan (Lily Evans), Ben Barnes (Sirius Black) Christian Cooke (Remus Lupin), Michael Angarano (Peter Pettigrew)
Middle: Tom Sturridge (Severus Snape), Bellatrix Black (Katie McGrath), Rosamund Pike (Narcissa Black), Toby Hemingway (Lucius Malfoy), Gemma Arterton (Andromeda Black)
Bottom: Eve Myles (Hestia Jones), Carey Mulligan (Marlene McKinnon), Penn Badgely (Frank Longbottom), Anna Popplewell (Alice Prewitt), Matt Smith (Ted Tonks)

But, who do you picture as the Marauders and co.?
Do you see the same as me, or different?
I'm just curious and to how different people interpret characters that we haven't really seen back before Harry and during the First War.
Thanks for answers!
