I’m guessing Alex Winter has a little more at stake here than Keanu does.

You were great in 'Poltergeist 2'.

New ‘Bill & Ted’ Definitely In The Works: Alex Winter Backs Keanu
Friday, September 24 by

Linkin Park?
Alex Winter has corroborated Keanu Reeves' story from earlier this week. William S. Preston, Esq. himself, told MTV that a third Bill & Ted film is in the works. They were struggling to find the right plot for a while, but now writers Chris Matheson and Ed Solomon have hatched a plot that they've begun writing.
The big issue, however, is what to do about George Carlin's character? Winter assures there's no way they would re-cast the part, so the trick now is to delicately work around his character. I'm hoping this means they'll use sophisticated Coke commercial CGI technology to bring him back to life. If I know Carlin, that's definitely what he would want to happen. (MTV)
