3. The Terminator
If the franchise can steal Matt Smith, it only seems fair that Doctor Who gets to nab the Terminator. Also, Arnie must be cheaper to hire these days, too. The timey-wimey nature of the Moffat Whoniverse would also match up nicely with the time paradoxes and alternate futures of the Terminator universe. Lets be honest, didnt Doctor Who, with Day of the Daleks, do the entire plot of the Terminator film 10 years early anyway? Maybe the Kraals could be revealed as being secret partners in the creation of the machines. The Doctor could utter the immortal lines, Ill be back and its about time! He could even get hold of that Tescelecta robot from Series 6, shrink himself down and have a one on one fight. Is it possible to get
too carried away...?
