Ben Affleck’s hostage thriller Argo may have nabbed the Oscar for best picture at Sunday’s Academy Awards ceremony. But its depiction of 1979 Iran as a seething hotbed of anti-American fervor is a stark contrast to the curiosity and warm hospitality that has greeted the relative handful of adventurous U.S. tourists willing to buck a longstanding State Department travel warning and years of governmental saber-rattling.

“There are many things that Americans justifiably find outrageous about the Iranian government” under President Mahmoud Ahmedinejad, guidebook guru Rick Steves told me after his 2008 trip.

But the peripatetic author also said he’d “never had so many preconceived notions torn apart,” and proclaimed the Middle Eastern lightning rod the most “surprising and fascinating” land he’d ever visited.

Americans Daniel Noll and Audrey Scott, who toured Iran in 2011, had a similar experience.

“Iranian people were often shocked to discover that we were American and that we were able to get a visa to their country. Once this fact set in, they often went over the top in welcoming us — everything from cordial greetings, to smiles, hugs, gifts and invitations to homes — especially when our guide was out of sight,” they wrote on their travel blog, Uncornered Market.

During my own 2008 visit, the eight Americans in our Canada-based tour group were treated like Hollywood celebrities. In my case, it included being engulfed by autograph-seeking schoolgirls at the Shiraz garden and tomb of the 13th century poet Sadi, and being invited to dinner at the home of an Isfahan shopkeeper whose illegal satellite TV beamed CNN and the latest American soaps.

To be sure,notes a recent story in the Washington Post, the vast majority of Iran’s foreign visitors (about 3 million in 2011) come for religious pilgrimages to Shiite holy sites.

“Due to its many restrictions, including required head coverings for women and a prohibition on alcohol, Iran is not an obvious choice for most Westerners,” an estimated 1,000 to 1,500 Americans per year among them. But, the story added, “the country’s allure lies in its seemingly countless ancient sites (including the ruins of Persepolis, a 2,500-year-old palace complex), its reputation for hospitality and, for some, its forbidden quality.”

“Most Americans’ perceptions of Iran are limited to images of Ahmedinejad delivering anti-American speeches and crowds chanting ‘Death to America!’ with the blessing of Supreme Leader Ayatollah Khameini,” says a 2012 story in The Atlantic. “Yet a 2009 World Public Opinion poll found that 51% of Iranians hold a favorable opinion of Americans, a number consistent with other polls, meaning that Americans are more widely liked in Iran than anywhere else in the Middle East. The U.S. favorability rating isn’t even that high in U.S. allies India or Turkey.”

As for Argo‘s take on the real-life rescue of six Americans caught in the Iran hostage crisis, the former Canadian ambassador featured in the film said it does does little to dissuade notions that Iran is “one long revolution and riot.”

Ken Taylor told Canada.com that he spent almost three years in Tehran and never felt in jeopardy, and described Iranian hospitality as “warm and genuine.”

“The amusing side,” he added, ” is that the script writer in Hollywood had no idea what he’s talking about.”
