When Iris talked to Travis

There's an understated scene in Taxi Driver (1976) that shows the vulnerability of an anti-hero. Robert De Niro's iconic Travis Bickle meets Jodie Foster's nubile Iris in a shady hotel room. His intention is to save her from the pimp (Harvey Keitel) who is obviously misusing her innocence. The initial dialogues exchanged between Travis and Iris is not extraordinary. She is behaving with him the way she would with any other customer while he rejects all her advances. Logic doesn't dawn upon her until the moment he shoves her onto the couch. In a different universe, that's something a Prem Chopra or a Ranjeet would do before raping the hero's sister/wife/dog. But in this case, Travis is trying to do something right. After she gathers herself from the push, he tells her he's not like others and he REALLY wants to help her escape even though it isn't established whether she wants the same or not. However, he makes her promise him to have breakfast at 1am—prostitution doesn't agree with sunrise for a reason—the next day. Before he leaves the room, he walks back to her and introduces himself before cupping her left cheek complimenting "Sweet Iris" to her amused look. That also happens to be the sweetest moment in the movie, seconded by the final scene when he refuses to accept fare from Betsy before driving away into the night.

N.B. If you haven't watched this movie, you deserve whatever spoilers i (unintentionally) let out above.

Why doesn't Leo turn into a chameleon?

He's indubitably one of the finest actors in recorded history. And he has bedded so many supermodels that he must be knowing Victoria's secret. His playboy image notwithstanding, he brings to his craft a touch of unforeseen dedication. But Leonardo DiCaprio is rarely seen in heavy makeup. Or crazy costumes. Or for that matter, a makeover. He finally managed to break his onscreen good-guy image with a racist act in Django Unchained last year. Oh yes, he put on an accent in Blood Diamond and bulked up for J. Edgar although the awards didn't roll in. Speaking of which, his second film What's Eating Gilbert Grape earned him an Oscar nod. For the record, he played a mentally challenged boy in it with such panache that the drool-worthy Jack Dawson had to redeem him four years later. Of course his career literally launched into new heights post-Titanic with dismissible bumps in the middle. The new millennium saw him collaborate with bigwigs like Scorsese, Spielberg, Ridley Scott, Clint Eastwood, Nolan, Luhrmann and Tarantino. He's doing great but wouldn't it be greater to don on a mask for a change or build six-packs or something? Johnny Depp has been so much into character that you may not even remember the last time you saw his face in a film. Similarly, it's impossible to separate Wolverine from Hugh Jackman. Brad Pitt went a step ahead and wore a skirt in Troy. When was the last time Leo did something crazy or wasn't similar to how he looked like in his previous film? He'll be turning 40 in a couple of months and has already starred in 24 full-length movies. The Wolf of Wall Street will be 25th. Does he look different in the trailer?
