I don't know... the "feud" is public... So when someone asked Takei "Hey, did you invite Shatner", he said, "No".
Actually, when Takei was asked about inviting Shatner, the invitations had not yet been mailed out. They had a contact list of about 3,500 names and only 200 seats and he just wasn't sure if William Shatner would be able to make the cut. That's all. In the end, Shatner did get invited afterall so I don't understand what the hell Shatner is bitching about.
