Now in her 40s, Geimer has said she has forgiven Polanski and does not want him to serve jail time.
Swiss officials are waiting on an official extradition request from the United States, but may set bail for Polanski.
Temime said he is unsure why U.S. officials would act now, nabbing his client as he arrived to accept an award at the Zurich Film Festival. He's hopeful the judge will be sympathetic to Polanski's situation.
"I think it will be possible for the Swiss judge ... to make Mr. Polanski free as soon as possible," he said. "If he was released he could have some conditions, but first we have to make the request."
Polanski, who has had small, often uncredited roles in his films, rose to fame in the 1960s and '70s as the director of such movies as 1968's "Rosemary's Baby" and 1974's "Chinatown." He was briefly married to actress Sharon Tate, who was murdered, along with the couple's unborn son, in 1969 by a group of Charles Manson followers.
The French culture minister has denounced the United States for the arrest of Polanski, saying it is a "terrible thing and very unfair."
"Seeing him alone, imprisoned while he was heading to an event that was due to offer him praise and recognition is awful. He was trapped," French Culture Minister Frederic Mitterrand said at a news conference Sunday. "In the same way there is a generous America that we like, there is also a scary America, that has just shown its face."
Mitterrand said French President Nicholas Sarkozy is paying close attention to the case and that the French consulate may try to visit with Polanski today if allowed.
"I'm offering my support to Polanski as a French citizen and as the minister for culture. Justice has been denied to him many times in his life, and beauty is something that he has brought though his films," he said, calling Polanski a "wonderful man" and "one of the greatest directors of all time.If the world of culture does not offer its support to Polanski, then that would mean there is no more culture in this country."
Polanski's team of U.S. attorneys -- Douglas Dalton, Bart Dalton and Chad Hummel -- also seemed surprised by the arrest.
"An issue related to the Swiss extradition matter is presently being litigated before the California Court of Appeal. We had hoped that this would be determinative of this case," they said in a statement to ABCNews.com Sunday. "We were unaware of any extradition being sought and separate counsel will be retained for those proceedings."
A spokesman for the U.S. Department of Justice, which is overseeing the case, declined to comment to ABCNews.com Sunday.
"We don't comment on matters of extradition, unless and until an individual is on U.S. soil," spokeswoman Laura Sweeney said, citing security concerns.
But the U.S. Marshals confirmed it has been watching Polanski's movements. A provisional arrest warrant was issued after the Marshals and the Los Angeles Police Department learned Polanski would be traveling to Switzerland via Vienna.
Two sources familiar with the case told ABC News that Polanski was arrested after authorities saw advertising on the Internet touting that he was going to attend the film festival in Switzerland. Apparently, the organizers for the event thought it was good for ticket sales and were using his appearance as a marketing tool.
