DaCostaBR: You and most others in this discussion are casting a Lara Croft with short shorts, huge boobs, sexy and unflappable in the face of danger. All one-liners and innuendo. Without realizing this character doesn't exist anymore. It hasn't for almost ten years.
If they do make this movie, they'll adapt Lara Croft as she exists in the games now, not as she was 20 years ago.
Breja: If a Lobo movie gets made, everyone expects it to be about Lobo from the 90s, not the current so called "Twilight Lobo" from the present comics. The Spider-Man we see in the upcoming Civil-War is the teenager in the classic costume, a character not seen in the comics for decades. For some characters, while they change and exist in many versions , there still exists a certain iconic look, one particular "definitive" version, and that's the one people expect to see in an adaptation, not some fleeting reimagining. For Lara Croft it's the big-boobed, guns-akimbo, shorts wearing bombshell.
I think you overestimate people's affinity for the classic Lara Croft, she and her games were a joke for a long time, that was the entire reason for rebooting them. So while that Lara may be more immediately recognizable to the general public, through pop cultural osmosis alone, I think the current version has more fans right now than the classic one, which doesn't seem to be particularly missed.
Not to mention that it is certainly the financial success of the game reboot that created this interest in rebooting the film series as well.
