A day after James Cameron participated in a Reddit AMA to promote the environmental documentary Years of Living Dangerously, Harrison Ford decided to give himself over to the process as well in support of the project. The iconic actor behind Han Solo in the Star Wars movies wasn't quite as candid as Cameron in answering fan questions, which was to be expected. As Ford is notoriously grumpy in most interviews. He did share his excitement about the Untitled Blade Runner Project, which may be a true sequel to the 1982 sci-fi classic.

No script is written yet, but Harrison Ford is looking forward to working with Ridley Scott, even despite their on set disagreements during the making of the first movie.

"I'm quite curious and excited about seeing a new script for Blade Runner if in fact the opportunity would exist to do another, if it's a good script I would be very anxious to work with Ridley Scott again, he's a very talented and passionate filmmaker. And I think it would be very interesting to revisit the character."

He was then asked if be believes Deckard is a replicant.

"I think that it's a wonderful storytelling mechanism for that question to be left unanswered. I love that people are still curious about it."

While Harrison Ford has been rumored for both Star Wars: Episode VII and Indiana Jones 5, he remained tight-lipped on both projects. He didn't comment on the idea of being replaced as Indiana Jones, either. Indiana Jones questions weren't completely off the table, as he compared the famous archeologist to his other alter ego, space smuggler turned rebel Han Solo.

"I think Indiana Jones was a lot of fun to do because of the places we went to and the adventures and the action. But Han Solo was also a huge part of my life."

Does he actually hate snakes, like Indiana Jones?

"I actually like snakes! When I was young, I was a boy scout nature camp counselor, and one of our projects was collecting snakes and creating an environment for them, so I'm quite familiar with snakes and think they're fantastic creatures."

Even with shooting believed to have already started on Star Wars: Episode VII, the actor wouldn't comment on his return as Han Solo. He did clarify an often-told story that he ad-libbed the response 'I know.' When Princess Leia says 'I love you." In Star Wars: Episode V - The Empire Strikes Back.

"It's not really an ad lib, it was a suggestion, and movie making's a real collaborative process at its best. You don't ad lib it, you suggest it and then you try something in rehearsal and then you agree. So it was my suggestion, because I thought it was more of a character line than what was written, but the director and Carrie Fisher and I all thought it was a good idea at the time so we did it."

That seemed to be it in terms of answering Star Wars questions. When asked who shot first, Han or Greedo, he responded in Ford typical fashion.

"I don't know and I don't care.

He seemed equally flippant about whether Han Solo or Indiana Jones would win in a fight.

"The promoter would win."

Harrison Ford will next be seen in The Expendables 3. He explains why he took on the role.

"I was on my way to Indonesia to do Years of Living Dangerously, and halfway around the world. And the location for The Expendables 3 was right on the way, and they asked me for a relatively short period of time, and it seemed like fun. I hadn't seen the films but I looked one of them and i thought it was kind of funny, so I thought why not?"

He also commented on his cameo at the beginning of the recent sequel Anchorman 2: The Legend Continues.

"It was goofy. I hadn't seen Anchorman: The Legend of Ron Burgundy, it was only one day's work, and I knew that it was very popular, and I admired the talents of the people involved, so I went to do it and had a great time, I enjoyed it. I still haven't seen it though."
